Why should air coolers be kept higher up in the room, and not down like the heaters?

Expert Answer:

Cool air is denser so it moves down whereas warm air is lighter so rises up hence convection currents are formed that helps in circulating the cold air and keeps the room cool.

If the air cooler is not kept higher up, then the cool air will remain at the surface layer and warm air will remain at the top, hence no circulation of air will take place and room will remain warm.
