Evaporation primarily occurs when the surface temperature of a material is warmer than the dew point. When surfaces are warmer than the dew point, the air above them can hold more moisture, allowing water to transition from a liquid state to a gaseous state. This temperature difference encourages moisture to evaporate efficiently.

In scenarios where surfaces are cooler than the dew point, condensation tends to happen instead; moisture in the air will condense on the surface, leading to increased humidity levels and potentially promoting water damage. When surfaces are at the same temperature as the dew point, a state of equilibrium is reached, where evaporation and condensation are balanced, preventing significant evaporation from occurring. The choice indicates that for effective evaporation to take place, maintaining surfaces at a temperature above the dew point is essential.
