Question

Why must you put an air conditioner in the window of a building, rather than in the middle of a room?

Step-by-Step Solution

Answer

We must put t an air conditioner in the window  to cool the room effectively.

Step 1: Given

Air condition is put in window. 

Explain why?

Step 2: Explanation

An air conditioner works on hot and cold reservoir concept. It considers outside of the house as a hot reservoir and room as a cold reservoir.

It works by extracting heat from room and emitting it outside. It will absorb the heat from a room and will transfer it to outside,when it is placed in a window of the room. In this way, the room will be cooled effectively by the air conditioner.

If we put in the middle of the room then the extracted heat will be thrown back to the same room, so it will not have much cooling effect on the room.

So it must be placed in a window.
