Answer:

Sublimation and evaporation are terms used to describe phase transitions of matter.

Sublimation is the transition of solid phase into gaseous phase. During this phase transition, the matter does not go through a liquid phase. The solid directly turns into a gas. This reaction is an endothermic reaction since chemical bonds between molecules should be broken down in order to release them to air. Since energy is released when chemical bonds form energy should be given in order to break them. Therefore, it is endothermic. This energy is calculated as the enthalpy of sublimation.

Evaporation is the transition of liquid phase into gaseous phase. This is an endothermic process. The intermolecular forces between molecules in liquid should be broken down in order to form its vapor. This reaction requires energy. Therefore, it is an endothermic reaction. This is the opposite reaction of condensation. Evaporation is directly related to the temperature. When the temperature is increased, the rate of evaporation is also increased.
