. Evaporation of water is


A: a process in which neither heat is evolved nor absorbed

B: a process accompanied by chemical reaction

C: an exothermic change

D: an endothermic change

 

Best Answer

Explanation:

  • In the process of evaporation of water, water is first taken to a temperature of  then the water receives the energy needed to convert the liquid molecules into vapor molecules.
  • Therefore, in both processes, temperature increase and phase change energy are required. And since then, any reaction requiring energy is an endothermic process.

Final answer: 

The correct option is D: an endothermic change
