OK, I think I've got it.
I'm assuming your reasoning is purely Newtonian -- you are using a

air density inside is lower that air density outside.

This obvious fact from hot air balloons and rising smoke is also the case
in constant volume. Just do the math if you can't see what I mean.

Now I think I am wrong. I forgot that higher speed makes bouncing more
frequent so the effect cancels out. But the horizontal effect is still
there. So it is still true that hotter gas in constant volume becomes
lighter. Unless something is happening at the walls.

Imagine a ball on lying at rest in a box. This is equivalent of a cold
gas. All pressure from the ball
