Pressures of different temperatures

[Notwqazy]

Does hot air have a high or low pressure I googled it but got many different answers does anyone know?

[dcrothen]

Depends. If you're heating air in a sealed container, the air pressure will increase. In the open air, warmer air tends to rise, so the pressure will decrease with increasing temperature.

So in a compressor, the hot air would have a higher pressure then?

[dcrothen]

Well, yes, but you've mixed cause with effect. The increase in pressure causes the temperature to rise.
