desalination of water water‚ desalination of‚ process of removing soluble salts from water to render it suitable for drinking‚ irrigation‚ or industrial uses. The principal methods used for desalination include distillation (or evaporation)‚ electrodialysis‚ freezing‚ ion exchange‚ and reverse osmosis. In distillation saltwater is heated in one container to make the water evaporate‚ leaving the salt behind. The desalinated vapor is then condensed to form water in a separate container. Although long

Water as a Universal Solvent * Because of its high polarity‚ water is able to dissolve most substances. * In a solution‚ the positive hydrogen side of water is attracted to the negative parts if the compound it is dissolving while the negative oxygen is attracted to the positive parts * “Like dissolves like” – describes whether one substance will dissolve in another. Water for example can’t dissolve nonpolar substances Concentrations on Solutions * Solvent: The liquid

Water Shortages Water has been one of our natural resources that we have used throughout time in many different ways. We have developed ways to make it more available and use it to create energy. However‚ because we have made it more available‚ we have developed issues that waste our good clean water‚ take old pipes that have been used to transport water across cities for example. Because they are so old‚ they tend to waste about 7 billion gallons of water every day (CQ Report‚ 2010‚ p.531). And

Determining the Ratio of Circumference to Diameter of a Circle In determining the ratio of the circumference to the diameter I began by measuring the diameter of one of the si objects which contained circles‚ then using a string‚ I wrapped the string around the circle and compared the length of the string‚ which measured the circumference‚ to a meter stick. With this method I measured all of the six circles. After I had this data‚ I went back and rechecked the circumference with a tape measure

Water purification is the process of removing undesirable chemicals‚ biological contaminants‚ suspended solids and gases from contaminated water. The goal is to produce water fit for a specific purpose. Most water is purified for human consumption (drinking water)‚ but water purification may also be designed for a variety of other purposes‚ including meeting the requirements of medical‚ pharmacological‚ chemical and industrial applications. In general the methods used include physical processes such
