Question

WHY IS IT SAID THAT TO KEEP A ROOM COOL ,WE HAVE TO PLACE THE AC ON THE TOP OF THE ROOM AND TO MAKE THE ROOM WARMER ,THE ROOM HEATER MUST BE KEPT AT THE BOTTOM?

Answer 1

This is because hot air rises up and cold air settles down.

Answer 2

It is because ac gives cold air which is heavier than the hot air so,the cold air goes down and the warmer air goes up so,ac was placed on top of the room.room warmer was placed in the bottom because it gives hot air which is lighter than the cold air and the hot air goes up.
