Water pollution is the contamination of water bodies (e.g. lakes‚ rivers‚ oceans and groundwater). Water pollution affects plants and organisms living in these bodies of water; and‚ in almost all cases the effect is damaging not only to individual species and populations‚ but also to the natural biological communities. Water pollution occurs when pollutants are discharged directly or indirectly into water bodies without adequate treatment to remove harmful compounds. Contents [hide] • 1 Introduction

Water has many unique properties that make life possible on Earth. One property is cohesion. The cohesion property is properly defined as the binding of water molecules by hydrogen bonds. Water has this property as a result of the chemical bonding between water. Cohesion of the strong hydrogen bonds allows the water molecules to stick together‚ almost as a unit of one. A force exerted on one of the molecules will be exerted on all of the adjacent molecules as a result of cohesion. Cohesion‚ often

The Miracle of Zam Zam Water Come the Hajj season‚ and I am reminded of the wonders of Zamzam water. Let me go back to how it all started. In 1971‚ an Egyptian doctor wrote to the European Press‚ a letter saying that Zamzam water was not fit for drinking purposes. I immediately thought that this was just a form of prejudice against the Muslims and that since his statement was based on the assumption that since the Ka’aba was a shallow place (below sea level) and located in the center of the

“Holy Water” by Didion was a wonderful and informative essay on the importance and lack of water in Western America‚ especially focusing on California and New Mexico. This essay was intended to show us the importance of water and how quickly we can run out of it. Didion wanted to show us that water is an everyday item that most people‚ myself included take for granted amongst many other things. Holy water is not about church‚ however‚ Didion has a religious view of her water and she encourages

Water has importance inside cells and externally. This may be because it has interesting chemical and physical properties; it can be found naturally in all three of its states. However its molecules are bonded together by hydrogen bonds‚ this raises its melting and boiling points‚ i.e. its boiling point would be -120¢ªC rather than 100¢ªC. Also because it contains slightly negatively charged oxygen atoms and slightly positively charged hydrogen atoms making it polar. <br> <br>Water has been called

Bottled Water vs. Tap Water Water is vital to human life. Humans can live for several weeks on water alone. However‚ they cannot survive for more than a few days without it. In fact‚ a human’s body primarily consists of 55% to 78% water (Geri Walton.) Therefore‚ we need water. Life cannot exist without water. While some people prefer drinking bottled water‚ others prefer drinking tap water. In fact‚ controversy has been placed on the quality and safety of drinking bottled water versus drinking

Complexometric Determination of Water Hardness Mike Monaghan CHM 152LL 01/27/2013 Abstract: What can be found from this experiment is as follows‚ Introduction/Background: This lab was about determining water hardness. Water hardness is the amount of metal ions in the water. The most common found ion in the water is calcium ions and typically with a charge of +2. Water hardness plays a big significance in our daily life because to many metal ions in our drinking water can have adverse effects

Ecology Essay Water makes up 75% of your body and is absolutely necessary for living. But do we know what we are drinking when we drink bottled‚ Recycled‚ and tap water? You might think it really does not matter‚ i mean they are all the same clean water right? Well‚ according to Rebecca Ephriham water that individuals and our families drink could contain deadly toxins‚ and can even cause cancer and other life threatening diseases. Some water is much cleaner than others and a much better choice for
