is covered with water. That may， at first， sound like a huge amount of water. But do you know only 2.53% of it is fresh water？ Furthermore， most of the fresh water is at the North Pole and South Pole. This means only a limited amount of water is available to human beings. A man can live without food for six or seven days， but he can live no longer than three days without water. Because water is such an important resource for our existence， we must learn to save and protect the water that we have. Though

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.

bad‚ however‚ defining quality is subjective and identifying quality can be difficult due to differing opinions (Gopee and Galloway‚ 2014). The Department of Health (DH) published a report called High Quality Care for All (DH‚ 2008) to express their goal of making quality of care the most important aspect of the National Health Service. The report defined quality into areas of care that is effective‚ evidence based‚ personalised and safe (DH‚ 2008). These main areas of quality have since been the foundation

Due to the people of the United States drinking billions of gallons of water daily‚ the amount of purified water we drink is starting to run out which is causing a problem already. Psychological studies have shown humans still don’t accept water being reused even after knowing the water is purified and perfectly clean. Advocates are still against ultraviolet machines being used to clean and purify water. While some people believe that drinking recycled water is both repulsive

WATER OUR LIFELINE Water is a transparent fluid which forms the world’s streams‚ lakes‚ oceans and rain‚ and is the major constituent of the fluids of living things. As a chemical compound‚ a water molecule contains one oxygen and two hydrogen atoms that are connected by covalent bonds. Water covers 71% of the Earth’s surface.[1] It is vital for all known forms of life. 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

Does This Thing Work? It operates on a 100 year old proven technology called electrolysis. Whenever you place two pieces of metal in water‚ and apply electricity‚ the water separates into it’s basic molecules‚ Hydrogen and Oxygen (H2O). If you look at the picture on the left‚ you will see H2O molecules connected together in their liquid form which is WATER But when you apply electricity (from your car battery)‚ the molecules separate and form a GAS (called HHO) which is a mixture of Hydrogen

Water: the source of life Water is an indefinable element. It can be destructible and wipe out the strongest forces in the world while it was also the beginning of life. It gives a lot but it can take back more than that. Water is one of the four elements of nature. It’s represented in the liquid form while earth is sold‚ air is gas and fire is the in-between of all. Water is important to every living thing. For plants it’s absorbed from the soil‚ for humans it’s for drinking and use for various

Water is a chemical compound with the chemical formula H2O. 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 (water vapor or steam). Water also exists in a liquid crystal state near hydrophilic surfaces. Water is considered a purifier in most religions. Major faiths that incorporate ritual washing (ablution) include Christianity
