The process of evaporation of a liquid is accompanied by 

a) Increase in enthalpy 

b) Increase in entropy 

c) Decrease in Gibbs energy

The process of evaporation of a liquid is accompanied by

(a) Increase in enthalpy as heat energy is absorbed.

(b) Increase in entropy as vapour has more randomness than liquid.

(c) Decrease in Gibbs energy as the process is spontaneous.

So, a, b and c all statements are correct.

Therefore, option D is correct.
