when the air expands,
Answers
Answer:
As the molecules heat and move faster, they are moving apart. So air, like most other substances, expands when heated and contracts when cooled. Because there is more space between the molecules, the air is less dense than the surrounding matter and the hot air floats upward

Answer:
When the air expands, it becomes thinner due to the atomic collision decreases.
This is the reason air becomes thinner during the expansion time.
The temperature manages the ideal heat of the substance. If the air expands, the temperature automatically decreases in a simple way.
So, the air becomes thinner due to such a reason.
The temperature is not directly passed on to the energy density.
It manages the average number of molecules.
