Causes for water crisis: India has built mega dams for irrigation, but her water management system has not received due attention. We are told that water crisis has touched millions people across several states.

Arsenic contaminated water made the problem more grave. During the monsoon, many areas of India are flooded, causing widespread damage to life and property and this enormous quantity of water is allowed to flow down into the sea. If the rain water is harvested and preserved in tanks and reservoir regularly, it may help us to tide over the water crisis. Other molecules, as small as water eg CO2 , change from liquid to gas at temperatures far below that of water.

It is also the Hydrogen bond which is responsible for the large amount of heat energy needed to convert water from liquid to gas. Water is therefore a great stabilizer of temperature which is essential to the survival of life on this planet. It accounts for more moderate temperatures near large bodies of water. This property is also exploited by many living organisms.

Sweat, and its evaporation is a vital cooling process for biological mammals and depend greatly on the large amount of heat energy required to break the hydrogen bonds between water molecules. Hydrogen bonding maintains the integrity of the water molecule during chemical reactions.

Other compounds undergo chemical changes ionization , where as water will maintain its chemical integrity. As a result water is a poor conductor of electrical current. In conclusion, three main unique features which are the consequences of hydrogen bonding in water are: These and other unique properties of water are responsible for the important role that water plays in life. It provides the medium in which most biochemical interactions occur. Some biochemical reactions water is involved in are: Water is the home for many animals, plants and micro-organisms.

Water is involved in the cycling of all other material by living things both on a local and global scale. Water has a number of unique and unusual properties that are responsible for its important roles it plays in the biosphere. Water has unusually high boiling and freezing points compared to other compounds with similar molecular structure. A comparison of boiling and freezing points can be seen in the following chart.

Notice only water has a boiling and melting point that exists within the range of life. The boiling point of water is a unique oC results is and the freezing point is a remarkable 0oC due to the fact of the polar nature of the water molecule and hydrogen bonding. Two important, but not unique, properties of water for life are that water is liquid at normal temperatures over much of the earth and that water is transparent.

If water were not liquid, nutrients could not flow from soil to the roots of plants, blood could not circulate, and bodies of organisms would be so rigid that they could not move. If water were not transparent, light could not penetrate through cellular protoplasm into chloroplasts to drive photosynthesis in plants, you would be blind because light could not penetrate through the vitreous humor to the retina of your eyes, and light could not penetrate into lakes to allow growth of phytoplankton.

Clearly life cannot exist without the amazing properties of water. A solvent is a substance capable of dissolving another substance solute to form a homogeneous mixture solution at a molecular level. The polar nature of water makes it an excellent solvent especially with other polar compounds such as salts, alcohols, carboxylic compounds and many more. More substances dissolve in water than any other known substance. The versitility of water as a solvent allows it to serve as the medium of transport for so many materials.

This is true both for individual organism and for the biosphere as a whole. The essential transport systems including blood, lymph, and urine are all water based. Water is the only substance where the liquid state is heavier than the solid state. All other substances the solid form is denser than the liquid form.

Since the density of ice is less than that of liquid Walter, ice floats on water. It is very significant that ice expands and floats on water because if lakes and streams froze from the bottom to the top, aquatic life would not even exist, and climate and weather patterns would be altered drastically.

This is an important quality of water because as ice forms it floats on top of the water. It acts to provide a thermal blanket for the rest of the water beneath and all its many life forms. This is important because if water behaved like all other substances, water bodies would freeze from the bottom up and in most cases would never thaw completely during summer.

This would have a dramatic cooling effect globally and would impact all life on earth. We see examples of this all the time. For example, under the summer sun at the beach, sand will increase in temperature to the point where it is too hot to walk on, whereas the water temperature is still cool, even though both are heated by the same amount of solar heat energy.

It boosts energy level and makes up for the water lost through perspiration. To regulate the body temperature, stay energized, improve motivations and do away with fatigue, you must drink plenty of water.

Athletes can improve their physical performance by drinking water in large quantities. If you are dehydrated, you can easily get migraine attack or headaches.

To beat a headache, it is must drink plenty of water. As per the latest researches, water can prevent a headache and may even manage the ache. The problem of constipation is characterized by difficulty in passing stools and infrequent bowel movements. Improving on the fluid intake is very much the part of the treatment protocol. Young and elderly, suffering from constipation, must try and consume maximum water to stay hydrated. Painful clumps of urinary stones may form in the human kidneys if there is a deficiency of water.

Among the various diseases, kidney stones are common. If you consume loads of water, a greater volume of water will pass through your kidneys to keep the system clean. Thus, the concentration of mineral will be diluted and it will be less likely to develop mineral crystals of urine. In short, you can decrease the probability of kidney stone formation.

Apart from the above-mentioned uses and applications of water, there are several others. It can help you prevent hangovers just after alcohol consumption. It also aids in weight loss. Water improves metabolic rate and satiety.
