Water Assignment
Water is the most abundant compound on Earth’s surface. It covers 70% of the plant, it exists in nature as a liquid, solid and gaseous states.(1) As standard temperature and pressure it is at a dynamic equilibrium between liquid and gas states this means the substance moves between the states at an equal rate, meaning there is no net change(2). At room temperature water is a tasteless and odorless liquid, it’s also almost colorless with a hint of blue. Many substances dissolve in water therefore rarely pure and known as the universal solvent.
Structure of Water
Water is a very small molecule consisting of the two most common reactive elements known (3), these are two hydrogen atoms covalently bonded to one oxygen atom. However, shared electrons in water are not evenly shared. Oxygen attracts electrons much more strongly than hydrogen, this results in a slight positive charge on the hydrogen atom and a slight negative charge on the oxygen atom. These charge difference lead to hydrogen bonding, this is where slightly negatively charge atom (oxygen) bonds to a slightly positively charged hydrogen this means that water molecules hydrogen-bond together a lot. The molecules then form a network that allows it to move around in whilst continually making and breaking hydrogen bonds. This explains why the boiling point of water is 100 degrees celsius because as soon as a hydrogen bond breaks it makes another one.
However, as the temperature of water is reduced, water moves less because it is lacking kinetic energy. Water forms more hydrogen bonds and they are not so easy to break. The water becomes solid and the hydrogen bonds hold the structure in a semi-crystalline form known as ice.

Salt Water Assignment

...Chemistry Assignment: Boiling Water Mrs. Goodyer Due Date: 21 July, 2006 Ben Graham Aim: To observe whether salt levels in water will alter boiling temperatures and times. Hypothesis: I hypothesise that adding salt to the water will raise the boiling temperature of water and lessen the time it takes to boil. This hypothesis is due to the ebullioscopic constant of water and the high heat capacity of water and low heat capacity of salt. Equipment: Beaker or saucepan Bunsen burner or hotplate Thermometer 45 grams of salt Stopwatch or timer Method: A saucepan was filled with 100ml of water. Its temperature was observed and recorded before the saucepan was placed on the hotplate. The timer was started as soon as it touched the hotplate. The thermometer was held in the water, not being allowed to touch the bottom of the saucepan. Every 30 seconds, a reading was recorded from the thermometer. Once the reading had been the same for one and a half minutes, the experiment was stopped. The experiment was repeated 4 times in total. The experiment was then repeated, but 15 grams of salt was added before heating started. Again, it was repeated, but with 30 grams of salt. The recorded results were then categorised, organised and displayed in appropriate......

...‘Water is essential for life’. It keeps our body hydrated, it is healthy, and helps carry oxygen to our brain (blood cell). Without water, we would all shrivel up and die. After all, our body is made up of 70%water! But there’s more to water than you think. In the next few paragraphs, you will learn more about water than you would ever want to and find some amazing facts! You all know that humans are made up of 70% water, right? Our lungs, brain, and heart all are made up of mainly water. But what about a chicken’s lung? Or a worm’s brain? Or even an elephant’ heart? It might surprise you or it might not, but chickens, worms, and elephants are all made up of 72% water! Think of how big an elephant is. More than half of that is water. That’s a lot of water! Drinking a glass of cold, pure water? Well, next time you drink a glass of water, think about this. That glass of water has been around longer than you. Water is continuously recycled and never lost. The water you drink is the same kind of water that dinosaurs used to drink! Millions and millions of years old! Of course though, water can get contaminated and then we humans have to purify it to make it fit to drink. Did you know that all foods have at least a little bit of water in them? All food has some water in it, even carrots! ANYTHING YOU CAN THINK OF! Bread has water in it! Cheese has water in it! Even eggs have some water in them! So don’t think that meeting your daily requirement of 8-10 cups of water is that......

...demand at the water refilling stations – water stores that sell purified water – is now increasing. The quality of purified water conforms with the national standards for drinking water and is even better than the quality of water produced by traditional water supply systems in terms of removed impurities. Over the years, as the demand for cleaner water becomes higher, the price of household water purifiers and bottled water has become prohibitive. Water refilling stations managed by private entrepreneurs offer a cheaper and more convenient solution to the public’s drinking water needs than bottled water or the use of household filters. At present, about 3,000 water refilling stations have proliferated nationwide. They sell purified water of comparable quality with bottled water at a lower price. For example, the current price per gallon of refilled purified water in Metro Manila ranges from P 50 to P 120 per 5-gallon container or about P 2.50 to P 6.00 per liter while the bottled water is sold at P 12.00 to P 25.00 per liter. Household filters, on the other hand, cost P 5,000 to P 25,000 per unit ( 1 US $ = P 56 in 2004). In Metro Manila, most of the water refilling stations are connected to the pipes of two concessionaires: Maynilad Water Company or Manila Water Company for their source of raw water while in other areas they opt to use private deep wells. The “potable water” supplied by the providers is then further purified by utilizing a combination of water......

...Water is a chemical compound with the chemical formula H 2O. A water molecule contains one oxygen and two hydrogen atoms connected by covalent bonds. Water is a liquid at standard ambient temperature and pressure, but it often co-exists on Earth with its solid state, ice, and gaseous state, steam (water vapor). Water also exists in a liquid crystal state near hydrophilic surfaces.[1][2][3] Water covers 71% of the Earth's surface,[4] and is vital for all known forms of life.[5] On Earth, 96.5% of the planet's water is found in seas and oceans, 1.7% in groundwater, 1.7% in glaciers and the ice caps of Antarctica and Greenland, a small fraction in other large water bodies, and 0.001% in the air as vapor, clouds (formed of solid and liquid water particles suspended in air), and precipitation.[6][7] Only 2.5% of the Earth's water is freshwater, and 98.8% of that water is in ice and groundwater. Less than 0.3% of all freshwater is in rivers, lakes, and the atmosphere, and an even smaller amount of the Earth's freshwater (0.003%) is contained within biological bodies and manufactured products.[6] Water on Earth moves continually through the water cycle of evaporation and transpiration (evapotranspiration), condensation, precipitation, and runoff, usually reaching the sea. Evaporation and transpiration contribute to the precipitation over land. Safe drinking water is essential to humans and other lifeforms even though it provides no calories or organic nutrients. Access to safe......

...Analysis: Bottled Water Causal Analysis: Bottled Water Ashlie Delaney Galen College of Nursing Bottled water has been around for centuries. While the aqueous solution in the bottle is imperative to your health, there are drawbacks to that liquid gold. And the package it rests in. Let us start of with a little history. One of the oldest discoveries of bottled water dates back to 1450 BC. There were murals painted the walls of ancient pharaohs tombs depicted canteens filled of the liquid. The Roman’s built one of the very first water transporting system. In 1767 water was first bottled in America under curative properties. Mineral water from New York was bottled commercially somewhere in the early 1800’s. In 1820, the popular Sarasota Springs sold their first bottled water. In the early times of commercially bottled water, it was marketed as a luxury drink to the wealthy and famous. It takes around 17 million barrels of oil to produce the plastic water bottles in The United States of America. Like bottled water, fossil fuels are harvested from locations around the world, processed, shipped and the consumed. Bottled water wastes a lot of fossil fuels. The burning of oil and other fossil fuels emits global warming pollution into the atmosphere. The price of bottled water is higher than the price of tap water, but in many instances, the water quality is the same. There is even a chance that an expensive bottle of water is just purified municipal tap water. The theory......

...Water is a molecule comprised of two hydrogen atoms (positively charged), and an oxygen atom (negatively charged)- bonded together by shared electrons. It is a V-shaped polar molecule, which gives water a high degree of polarity. In addition, water molecules are naturally strong, due to the interactions occurring between the hydrogen atoms, known as hydrogen bonding. Specifically, hydrogen bonding in water, accounts for some of its unique properties; such that it is denser in its liquid state than in its solid state (ice floats on water). Water is also the only substance that occurs naturally as a solid, liquid, or gas, and covers about 70% of the Earth’s surface (U.S. Geological Survey, 2000). Water is a very broad topic, and highly crucial to life on Earth. It is important to mention the movement of water throughout the planet, the usages of water, and the underlying scarcity of water. The Hydrologic cycle, more commonly known as the water cycle, is the movement of water between the Earth’s oceans, atmosphere, and land. There is continuous evaporation of water; uptake of water vapor into the atmosphere; precipitation onto the ocean and land surfaces; and the net atmospheric transport of water from land areas to the ocean. Essentially, the water cycle is the means of how the Earth’s constant supply of water is being recycled. It is imperative that this cycle exists, so that water is able to reach plants and animals; provide nutrients and sedimentary movements......

...not have access to potable drinking water. While many rural towns once had piped water, these systems have fallen into disrepair due to lack of maintenance. Similarly, a few villages had drilled wells with hand pumps near schools and clinics but have lost this infrastructure. Therefore, rural populations draw their water from unprotected springs or rivers located from 300 to 600 meters from the villages or from hand-dug wells, locally known as matsime. The matsime are primitive wells with an average depth of six meters, with a diameter of 1.2 meters and uncovered at the top. The water collected from rivers and matsime is used for bathing, washing clothes, cooking and drinking. Most of the households in the targeted communities do not have latrines. The majority of the population disposes of excreta in the open, rather than using latrines, thereby contaminating water sources and spreading diseases. * * Goals To decrease morbidity and mortality due to water-borne diseases through the provision of potable water from protected springs, construction of appropriate latrines reinforced by community-based water and sanitation education for 114909 people in Mbire Rural District Council. Objectives 1. Increase access to potable water for 114909 people. 2.

Water Utility Management Assignment

...Civil Engineering ASSIGNMENT 3 Compiled by: Petronella Buys Student Number: 9763554 Presented to: Mr. Andrea Vushe Course name: Water Utility Management Course code: WUM410S Deadline: 7 October 2015 The Willingness to Pay Experiments: Estimating demand for piped water connections in Sri Lanka. This paper shows how Willingness to Pay surveys can be used to gauge household demand for improved network water and sanitation services when a private sector transaction is considered. The survey included approximately 1800 households in the year of 2003. Using multivariate regression, it showed that a complex combination of factors drives demand for service improvements. While poverty and costs are found to be key determinants of demand, they also found that location, self-provision, and perceptions matters as well, and that sub-sets of these factors matter differently for sub-samples of the population. The simulations show that in this particular environment in Sri Lanka, demand for piped water services is low, and that it is unlikely that under the present circumstances then, the goal of nearly universal piped water coverage was going to be achieved. Policy instruments, such as subsidization of connection fees, could be used to increase demand for piped water, but it is unclear whether the benefits of the use of such policies would outweigh the costs. Contingent Valuation (CV) has been used increasingly in developing countries for improvements in water and sanitation......

...Most people know that drinking water is essential to human life. Without it, the human body will shut down and experience life-threatening health problems, or even death. However, many people tend to forget just how important water is to staying healthy and fit. The fact is, anyone who adopts a fitness regimen needs to understand just how important water is to a great workout and the role it plays in achieving optimal physical results. Working out will make you thirsty, but be sure you are drinking enough to compensate for your exercise? During one hour of intense exercise, the average person can lose a full quart of water just by sweating. To prevent dehydrating, it is a good idea to drink one glass of water for every twenty minutes of exercise. If you know you are prone to sweating a lot, you should be sure to drink even more. Drinking water during exercise is extremely important. However, it is just as important to drink water before and after a workout as well. If you are planning on a tough workout session, you should drink 3-4 glasses of water in the 3 hours before you start sweating. If your muscles are not hydrated when you begin working out, they will be more prone to cramping and injury. Dehydration is also linked to muscle soreness, so be sure your muscles are nice and hydrated before you start. After your workout, you will want to rehydrate your body with even more water. The optimal time for this is within the first two hours after you exercise. At a......

...As an aside, Mpemba was mocked by his teacher for claiming hot water freezes faster than cold water because it seemed to contradict thermodynamics. Moral of the story? Don't be so fast to dismiss the observations of a non-scientist just because they don't agree with what you think you know. In fact, that lesson probably applies to most academic disciplines and, perhaps, all of human knowledge. Skepticism of people's claims is important. The Mpemba effect occurs when two bodies of water, identical in every way, except that one is at a higher temperature than the other, are exposed to identical subzero surroundings, and the initially hotter water freezes first. The effect appears theoretically impossible at first sight. Nevertheless, it has been observed in numerous experiments, and we will see that it is in fact possible. Readers who are quite certain that the effect is forbidden by the laws of thermodynamics should pause for a moment to do two things. First, to try to explain, as precisely as possible, why it is impossible. And second, to decide how to respond to a non-scientist who insists that they have observed the Mpemba effect in a home experiment. Whether or not the effect is real, careful consideration of these tasks will bring up a wealth of important issues about the scientific method, that can be understood and discussed by students without any knowledge of advanced physics... To see how the effect might occur, it is useful to carefully think about why the...

...Water, War and Peace in the Jordan River Valley Introduction The Great Rift Valley extends longitudinally from northern Syria more than three thousand miles into southeastern Africa. Sweeping laterally across North Africa, Arabia, and Asia we find the world’s most immense expanse of deserts. At the crossroads of this desert space and Great Rift Valley, the Jordan River flows two hundred miles from its sources in Lebanon, Syria and Israel to the Dead Sea, the lowest point on Earth . This dramatic geographic setting is home to some of the most ancient and continuously sedentary civilizations in known history. In this essay I intend to briefly explore the ecological history, sources, and climatic changes of the Jordan River, and give an overview of its political history. In a more in-depth investigation I will inquire how population increases during the past century have contributed to both conflict and cooperation between the diverse inhabitants of the region. Focusing on the major issues of water usage, distribution, and control, I will examine the negotiations, agreements, treaties, development projects and international laws governing the use of water from the Jordan River watershed. How have war, land disputes, and peace affected the management and distribution of this water? What is written in legal documents, and how successfully have terms of agreements been implemented? What importance do the clauses about water in the recent Jordan/Israel peace accords......

...Water Life on earth evolved in water, and all life still depends on water. At least 80% of the mass of living organisms is water and almost all chemical reactions of life take place in aqueous solution. Water molecules are charged, with the oxygen atom being slightly negative and the hydrogen atoms being slightly positive. These opposite attract each other, forming hydrogen bonds. These are weak, long distance bonds that are very common and very important in biology. Water has a number of Important properties essential for life. * Excellent Solvent- Because it is charged water is a very good solvent.Charged molecules such as salts, sugars, amino acids dissolve readily in water and are called hydrophilic. Uncharged molecules such as lipids do not dissolve so well in water and are called hydrophobic. * High Specific heat capacity- Water has a specific heat capacity of 4.2 J g-1 oC-1, which means that it takes 4.2 joules of energy to heat 1g of water by 1oC. This is unusually high and it means that water does not change temperature easily. This minimises fluctuations in temperature inside cells and it also means that sea temperature is quite constant. * Latent heat of vaporisation- Water requires a lot of energy to change state from a liquid to a gas, and this is made use of a cooling mechanism in animals (sweating and panting) and plants (transpiration). As water evaporates it extracts heats from the surrounding area, cooling the organism * Latent heat......
