Difference Between Vaporization and Evaporation with ...

During evaporation, the liquid state of matter is turned directly into a gas. Vaporization is usually a fast process and requires less amount of energy. Evaporation is generally a slower process and requires more energy as the molecules have a high tendency to convert into the vapour phase. During vaporization, all of the water can turn into gas.

How surface area affects the rate of evaporation?

May 12, 2020 The surface area affects evaporation because if more area is exposed to air, allowing water molecules acquire more heat energy from the surroundings. Due to the increased heat energy (kinetic energy), there is more rapid movement of the water molecules which helps them to overcome the force of attraction and evaporate. Click to see full answer.
