MS PS3 3

In the winter, hot air from the heater rises, making air near the ceiling warmer than the air near the floor. many ceiling fans have a setting said to reduce heating energy costs. How could that work?

• The ceiling fan is in contact with the ceiling and heats the room by conduction.

• The spinning blades radiate heat through the air and heat the room by radiation.

• The spinning blades cause the hot air on the ceiling to mix through the rest of the room and heat the room by convection.

• It cannot work, Ceiling fans can only cool rooms.
