Answer 2

Evaporation of a liquid takes place at all temperatures.

• The molecules on the surface gain energy from the lower molecules and escape during evaporation. It happens at all temperatures because the molecules on the surface gain energy from the environment and escape out of the surface.
• More evaporation occurs when the surface area of the solvent for evaporation is larger. Because there are more surface molecules per unit of volume that can escape, a substance with a larger surface area will evaporate faster.
• As the temperature rises, the rate of evaporation increases.
