Drinking water or potable water is water safe enough to be consumed by humans or used with low risk of immediate or long term harm. In most developed countries‚ the water supplied to households‚ commerce and industry meets drinking water standards‚ even though only a very small proportion is actually consumed or used in food preparation. Typical uses (for other than potable purposes) include toilet flushing‚ washing and landscape irrigation. Chlorination is the process of adding the element chlorine to water as

Water Transport The movement of plants from water to land has necessitated the development of internal mechanisms to supply all the parts of the plant with water. As discussed in Plant Classification‚ Vasular Tissues ‚ tracheophytes (including virtually all terrestrial plants except for mosses and liverworts)‚ have developed complex vascular systems that move nutrients and water throughout the plant body through "tubes" of conductive cells. The vascular tissues of these plants are called xylem

WATER RESOURCES The sources of water that are useful to human life are called water resources. Uses of water include agricultural‚ industrial‚ household and recreational activities. The majority of human uses require fresh water. 97 percent of the water on the Earth is salt water and only 3 percent is fresh water; slightly over two thirds of this is frozen in glaciers and polar ice caps. The remaining unfrozen fresh water is found mainly as groundwater‚ with only a small fraction present above

Thesis Statement: Water pollution is bringing down the economy‚ destroys the beauty of nature‚ and causing harmful dreaded diseases and sickness in precious health of many individual. INTRODUCTION Water pollution progresses every day in our lakes‚ oceans‚ rivers‚ and other bodies of water that we see and use in many ways. Water is essential for all living things to survive‚ yet people still pollute it. It’s pretty sad to be taking a trip to the beach with your family and you get there to see

Deionized Water vs. Distilled Water Deionized and distilled waters are both processed forms of water. Deionized water is produced by filtering water to the point where it is free of ions. This ion-free water will strip ions from surrounding material‚ acting like a super-solvent. This is often used in semiconductor and other high-tech processing as a "soft" solvent and relatively cheap cleaning fluid. Distilled water is most often produced by vaporizing less pure source water (tap‚ salt or even

Salt Water or Fresh Water‚ Which Would You Prefer? Many people wonder‚ what big differences are between salt water and fresh water? Is it just water with salt versus water without salt? Those are some common questions people have. Most people ask about the differences‚ but they forget about the similarities of salt water and fresh water‚ as well. Did you know that Salt water and fresh water have very different plant and animal life? There are also a few complex fish that can live in both

Tap Water Vs Bottle Water Tap Water: Tap water is the most efficient water available. Unfortunately‚ it is also vulnerable to occasional contamination. This is usually locally due to damaged pipes. This type of problem can be fixed in a timely manner. For the most part‚ the water is not much different from bottled water. It can be consumed directly from the pipes without harm. Even when the water is contaminated it is usually not fatal. Water pipes efficiently carry water across the nation as

Introduction Water is necessary to life but it can be unhealthy too. In general‚ the water quality is poor in developing countries like Kenya. Water is a vector of diseases like yellow fever‚ diarrhea… Water purification is very important in these countries but people don’t have a lot of time to spare‚ they work or they are in the field and in general women must spend a significant amount of time walking to collect water. So we need to find a quick‚ easy‚ and economic solution that is as simple

property of water is that it is an excellent solvent. This is because of the chemical composition and physical attributes of water. Since water is polar‚ it allows water molecules to become attracted to different molecules. The attraction can be so powerful that it can disrupt the attractive forces of the different molecules. For example‚ water can be heavily attracted to salt that it can disrupt the forces that hold sodium and chloride‚ therefore dissolving it. The second property of water is its high

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
