Answer:
(a) Increase in temperature of water will increase
the evaporation of water. It is because, on increasing the temperature, kinetic
energy of water molecules increases and more particles get enough kinetic
energy to go into the vapour state.
This increases the rate of evaporation. Evaporation is the
surface phenomenon so it depends upon the exposed surface area. Higher the
exposed surface area of water, higher will be the evaporation. When common salt
is added to water then surface is occupied by the solvent as well as
non-volatile solute particles.
So, the escaping tendency of solvent particles decreases
and thus the evaporation of water decreases. Therefore, other options (b), (c)
and (d) will decrease the evaporation of water.
