Question

3. In a room it is best to place a room heater on the floor but an air conditioner near the ceiling. Why?

Answer 1

Answer:

The heater is placed near the floor because the air currents move upwards so the hot air fills up the whole room. Whereas, an air conditioner is placed near the ceiling because the cold breeze tends to settle down. ... So it is placed near the ceiling so that the whole room cools down.
