Question

Why are room heaters placed at or near the floor of the room?

Answer 1

Explanation:

HEATER is placed near the floor because hot air rises up and the room will be heatness will spread even. The density of air depends upon the temperature. If the density of air is high then it will settle in the bottom and if it is less dense and it will move upwards.

Answer 2

Due to the physical property of the air. Hot air, being lighter than the cold air tends to rise up (This is the same principle on which hot air balloons function, heating the air inside, which makes it rise upwards in air). So when hot air rises above inside the room, it pushes the cold air down and the cold air is then heated by the room heater, and rises. So this completes the cycle using natural circulation of air and helps in better heating of air inside the room.
