what's is hot air pressure explain? and what it is use for.
Answers
Answer:
Warm air is less dense and has a lower pressure associated with it. As the sun heats the ground, the air near the ground warms. Remember, heat is less dense than cold air so the warm air will rise. This rising motion creates a natural vacuum lowering the air pressure at the Earth's surface.

Answer:
If we're talking about a fixed volume of air, then hotter air is at a higher pressure. At a higher temperature, particles bounce off the inside of a container faster..because at higher temperatures particles are moving faster.
However…if you heat air and allow it to expand (like in a hot air balloon where the air can escape from the bottom if the balloon) the air becomes less dense because the particles move further apart….and so hot air rises…and in weather systems this effect creates areas of lower pressure.
So..it depends what you mean.
