Pdf115k, public health protection, the first obligation of any water supplier is to provide water that is safe gpa for consumption. In a world where an estimated 3 million people die every year from preventable waterborne disease, water systems in North America allow us to drink from virtually any public tap with a high assurance of safety. A safe water supply is critical to protecting the public health - the first obligation of all water suppliers. Without our modern water systems, diseases such as cholera and dysentery would be part of everyday life. In the United States, water utilities monitor for more than 100 contaminants and must meet close to 90 regulations for water safety and quality.
Water has a high latent heat of homework vaporisation, which means that when animals sweat and plants transpire water, takes energy from the organism when it evaporates and as a result cools the organism. Therefore water has many interesting and unusual properties which are fundamental for survival of all living organisms. Best Answer: The value of Tap. Water, how often do you think about your tap water? If you're like most, probably not often. And yet tap water delivers so many things that no other water can deliver. It delivers public health.
One of the most important properties of water is as a solvent. Water is slightly ionised which means that other polar molecules such as salts, sugars and amino acids will dissolve readily in water. This means water can be used for the transportation of such substances (notably in the bloodstream of animals and the xylem and phloem vessels found in plants) Water has an unusually high specific heat capacity; over twice the specific heat capacity of ice or steam. Water does not change temperature very easily and therefore minimizes fluctuations in temperature in cells and creates a remarkably constant sea temperature for aquatic organisms. As water is heated, the increased movement of water causes the hydrogen bonds to bend and break. As the energy absorbed in these processes is not available to increase the kinetic energy of the water, it takes considerable heat to raise water's temperature. Also, as water is a light molecule there are more molecules per gram, than most similar molecules, to absorb this energy. Heat absorbed is given out on cooling, so allowing water to act as a heat reservoir, buffering against changes in temperature.

This separation between negative and positive charges creates what is known as a polar molecule, meaning a molecule that has an electrical charge on its surface somewhere. Although the water molecule as a whole has no charge, the parts of it, the hydrogen wings and the oxygen body, do exhibit individual charges. The polarity of water allows it to join with other molecules, including itself. Water molecules can form hydrogen bonds, which give shape to water as a whole. Water has a high surface tension(Fig 2). The ability of water molecules to quickly break and re-form hydrogen bonds gives it a property called cohesion. Water's high amount of cohesion dark makes it "sticky" such that across the air-water interface,. Click the button above to view the complete essay, speech, term paper, or research paper.

Its uses in all living things cover a huge variety of everyday functions, which are important to the continuity of the organism. Water has obvious familiar properties, its colourless; It's tasteless; It's odourless; It feels wet; It's distinctive in sound when dripping from a faucet or crashing as a wave; It dissolves nearly everything; It exists in three forms: liquid, solid, gas; It can absorb a large. Water's unique properties are largely a result of its simple composition and structure. Water is composed of two hydrogen japanese atoms bound to one oxygen atom. The two hydrogen atoms are smaller the smallest atom there is, in fact, and they rest on both sides of the larger oxygen atom at an angle of 105. When the hydrogen atoms combine with oxygen, they each give away their single electron and form what is known as a covalent bond. Because electrons are more attracted to the positively charged oxygen atom, the two hydrogen's become slightly positively charged (they give away their negative charge) and the oxygen atom becomes negatively charged.
