1.	Water is a universal solvent. But alcohol also dissolves most of the substances soluble in water. Boiling point of water is 100^(@)C and that of alcohol is 80^(@)C. The specific heat of water is much higher than the specific heat of alcohol. (a) List out three possible differences if instead of water as the liquid in our body we had alcohol. (b)What value can you derive from this special property of water and its innumerable uses insustaining life on earth?
Answer» Solution :(a) I.Even a small raise in temperature in the surroundings will raise the temperature of the bodybecause the specific heat of alcohol is much less than the specific heat of water. In order to coolthe body more sweating will take place.II.As there is less H bonding in alcohol it will get evaporated FASTER. The alcohol will be evaporatedat such a fast rate that the liquid has to be ingested always.III.Ice which floats on water helps AQUATIC life to exist even in winter as water insulates the heatfrom liquid below it to go back to the surroundings. Solid alcohol does not have such specialproperties.(b)PRAISE is to the almighty that has so thoughtfully given such SPECIAL properties to water andmade it a liquid that could SUSTAIN life.
