Question

why does the rate of evaporation increases with increase in the temperature??

Answer 1

Increasing thetemperature of a body of water also often increases evaporation. This is because as thetemperature rises, the water molecules begin moving about more rapidly. This increases the odds that molecules will escape. Warmer air also affects the speed of evaporation.

Answer 2

with the increase in temperature the molecules of a liquid moves away from each other that is the intermolecular spaces increase thus in more temperature due to more intermolecular space intermolecular attraction decreases and so rate of evaporation increases that is there is more chance of the liquid to be converted into Gas state.
