Answer 1

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.

Answer 2

I think the thinner ok bye
