Statement II is true. Evaporation is a surface phenomenon, where liquid molecules gain enough energy to escape into the gaseous phase from the surface of the liquid. The rate of evaporation is directly proportional to the surface area exposed to the surrounding environment (air). Other factors affecting evaporation rate include temperature, humidity, and wind speed.
