Difference Between Sublimation and Evaporation

Difference Between Sublimation and Evaporation

Apr 29, 2022 Evaporation is the conversion of the liquid phase into the gaseous phase. Evaporation is also an endothermic process, and intermolecular forces between molecules of liquid should be broken down to form its vapor. So this reaction requires energy to break the bonds. Hence, it is an endothermic reaction.

Difference Between Vaporization and Evaporation - BYJUS

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.

Jan 16, 2022 When it comes to Evaporation, only non-living stuff is involved, but in Transpiration, only live tissue is. In contrast to Transpiration, which occurs solely during the day, evaporation occurs continuously (during the day and at night). Following Transpiration, the surface stays damp; but, after Evaporation, it becomes entirely dry.
