Evaporation occurs when water molecules on the surface gain sufficient energy to enter the atmosphere. However, the stronger intermolecular forces between the molecules of water are strongly attracted to one another and tend to remain in the liquid phase. When the temperature is raised (when heat is applied), more molecules gain the energy necessary to escape these intermolecular forces and enter the vapour phase.Therefore, the best answer is D.
