A fan produces a feeling of comfort during the hot weather because
Detailed Explanation:
A fan creates air movement that accelerates the evaporation of perspiration from our skin. This evaporation is an endothermic process that absorbs heat from the body, producing a cooling sensation.
The fan does not supply cool air (it merely circulates room-temperature air), nor does it significantly alter body heat radiation or air conductivity—it purely enhances evaporative cooling.
Therefore, perspiration evaporates rapidly, making Option 4 the correct answer.
