Solution

The correct option is D Only statement-2 is correct
Evaporation is the process of change of a liquid into vapours at any temperature below its boiling point involving only the surface particles. Thus, it is a surface phenomenon. Boiling is a bulk phenomenon as particles from the bulk of the liquid gain enough energy to change into the vapour state. When a high pressure is applied and the temperature is reduced, a gas can be liquefied.
Hence, the correct answer is option (d).
