Does warm air or cool air have high pressure? thanks
I cool air would have higher pressure than warm.
Warm air is less dense than cool air &, therefore, it would have a lower pressure than cool air. Warm air also rises more quickly b/c it is less dense.

To determine if warm air or cool air has high pressure, we need to understand the relationship between temperature and air pressure.
According to the ideal gas law, which describes the behavior of gases, the pressure of a gas is directly proportional to its temperature (when the volume and the amount of gas are constant). This means that as the temperature of a gas increases, its pressure also increases.
Therefore, warm air tends to have higher pressure compared to cool air. When air is heated, the molecules gain energy and move faster, which leads to more frequent and forceful collisions between them. These collisions create higher pressure.
On the other hand, when air is cool, the molecules have less energy and move slower, resulting in fewer and less intense collisions and therefore a lower pressure.
In summary, warm air has higher pressure, while cool air has lower pressure.
