Evaporation takes place more slowly at any temperature between the melting point and boiling point, and only from the surface, and results in the liquid becoming cooler due to loss of higher kinetic energy particles. Evaporation occurs at all temperatures at the surface of the liquid. Among the factors affect the rate of evaporation are;-

1. The temperature is higher, since then more molecules in the liquid are moving fast enough to escape from the surface,

2. The surface area of the liquid is large so giving more molecules a changes to escape because more are near the surface.

3. Wind or draught is blowing over the surface carrying vapour molecules away from the surface thus stopping them from returning to the liquid and making it easier for more liquid molecules to break free
