The importance of water Water is one of the weirdest compounds known to humans. The difference between the boiling point and freezing point of water is one of the largest ranges of any compound. It is this span of temperature that mirrors the range of where life can exist‚ from bacteria to humans. Water also has a very high specific heat‚ which means that it can absorb or lose much heat before its temperature changes. This is important in maintaining body heat in mammals. It also takes a lot of

Water polo is a team water sport. It is the oldest continuous Olympic team sport. The playing team consists of six field players and one goalkeeper with a maximum of six substitutes. The winner of the game is the team that scores more goals. Gameplay involves swimming‚ players passing the ball while being defended by opponents‚ and scoring by throwing into a net defended by a goalie. Water polo‚ therefore‚ has strong similarities to the land-based game of team handball. The frequency of ’man-up’

ESSAY ON WATER & ENERGY CRISIS IN PAKISTAN 1. INTRODUCTION: “Water is precious‚ use it wisely” says a notice placed in the bathroom of a five star hotel in Karachi. There could not be a sounder piece of advice but it should be given not only to the guests of the five star hotels but also to the entire citizenry of Pakistan. Pakistan is rapidly moving to the situation when it will begin to be ranked among the countries that have severe shortages of fresh water. Wise use of this precious resource

Complexometric Determination of Water Hardness by EDTA Titration Bonnie Abella Dr. Asmita Kane Budruk 2/09/2014 Abstract: the complexometric EDTA titration was used to determine the salt substance in the water. This technique for the unknown sample 154 produced a water hardness of 8.43 x105=mg/L CaCO3 from the collected data which corresponds to the typical value from the city of Tempe. Introduction When the water from the rain collects impurities by dissolving the

amounts of water consumed in the brewing process as well as washing and sterilizing procedures. It is estimated that between 4 and 7 L of water is required to produce 1 L of beer. Beer is the fifth more popular drink in the world so to meet this demand; large quantities of water are required. Water chemistry has an effect on the brewing efficiency as well as the taste‚ so water from water authorities must be treated in order to produce water which is acceptable for brewing. Demand for water has become

Complexometric Determination Of Water Hardness By Angelica Aquino CHM 152 LL January 5‚ 2013 METHODS: 1. Prepare an approximate 0.004 M disodium EDTA solution. To prepare this solution‚ weigh about 0.7-0.8 g of Na2EDTA and dissolve in 500 mL deionized water in your plastic bottle. Make to to shake the bottle to dissolve the salt. 2. Obtain a 250-mL Erlenmeyer flask and transfer a 10 mL of CaCO3 using a buret into the flask. 3. Measure 30 mL of deionized water and add it into the titration

Water Crisis in UAE Introduction Water crisis refers to the situation where the available water within a geographical location cannot meet the water needs of the population in that location. This prevalent situation has drawn considerable attention in most countries due to its severity to humanity. Because of the tripling of the population in the 21st century‚ the demand for water has remained considerably higher than the available clean and safe water. Despite the fact that the earth is covered

WATER RESOURCES What are water resources? Water resources are sources of water that are useful or potentially useful to humans. It is important because it is needed for life to exist. Many uses of water include agricultural‚ industrial‚ household‚ recreational and environmental activities. Virtually all of these human uses require fresh water. Only 2.7% of water on the Earth is fresh water‚ and over two thirds of this is frozen in glaciers and polar ice caps‚ leaving only

WATER IS LIFE Water is the one thing the world cannot survive without‚ without water it is impossible that a planet be inhabited‚ for example 70% the planet earth is covered in water thus it is thriving with living creatures‚ whereas mars the closest planet to earth; mars is a dead planet‚ it has no plants‚ no animals‚ all because of the absence of the life giving force that is water. Wherever we have water we find life‚ even the smallest of ponds can support life‚ grass will grow around it animals
