Question

Quizplus · Accepted Answer

Technician A is correct because heat is required to change the state of water from liquid to gas during evaporation. This heat is absorbed from the surroundings, resulting in a cooling effect. Hence, heat loss occurs during evaporation. However, Technician B is incorrect because the rate of evaporation is affected by air movement. Higher air movement increases the rate of evaporation as it removes the humid air surrounding the evaporating surface and replaces it with cool, dry air.
