When does evaporation occur in the drying process?

Evaporation during the drying process occurs as energy increases. This is because evaporation is fundamentally a process that requires energy in the form of heat. When the temperature rises, the water molecules gain enough energy to transition from a liquid state to a vapor state.

In the context of water restoration, this process is critical. As moisture is present in materials, the application of heat or warm air can enhance the molecular movement of the water, allowing it to evaporate more efficiently. This principle is often employed in water damage restoration to accelerate the drying of affected materials.

While moisture must indeed be present for evaporation to occur, the increase in energy is what specifically facilitates this transition from liquid to vapor. Thus, the assertion that evaporation occurs only as energy increases is the most accurate in terms of the drying process in water restoration.
