Question

It is recommended that air conditioners and ventilators should be fixed near the _______________of a room.

Answer 1

1. It is recommended that air conditioners and ventilators should be on the roof so as to ensure that proper convection takes place.
2. As hot air is less dense so it rises up and gets cooled by the air conditioner.
3. After the air gets cooled it settles down and hot air rises up and this cycle continues.
4. In the same way ventilators at homes and offices help in the circulation of air.

Hence, it is recommended that air conditioners and ventilators should be fixed near the roof of a room.
