Water is indispensable for life. What properties of water make it useful for all biological processes on the earth?
a) Water is a polar solvent due to which it is regarded as the ‘universal solvent’.
b) Water has a high specific heat capacity.

c) Water has low viscosity and high surface tension.

d) The density of water decreases below 4◦C.

e) Capillarity of water

Solution:

a) All living creatures’ essential substances are solutes that are dissolved in water and transferred from one location to another.

b) Specific heat is defined as the amount of energy necessary to raise the temperature of one gramme of substance by one degree.

c) Surface tension refers to the cohesion of water molecules on the fluid surface that takes up the least amount of space. The resistance of a fluid to flowing water is called viscosity.

d) When the temperature of water drops below 4 degrees Celsius, it expands. This reduces the density of the ice, causing it to float.

e) Water rises in capillary tubes, a feature that aids in the movement of water from the plant’s roots to other areas.
