Question

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.

Answer 2

Answer:

In a room it is best to place a room heater on the floor but an air conditioner near the ceiling because heater produces hot air which rises up making the air in the room warm whereas air conditioner is usually used in summer to keep the air cool and is placed near the ceiling so that the cold air spreads in the room making it cool.
