Yes, warm air is generally associated with low pressure.
Here's why:
- Molecular Activity: According to the reference, heating air increases the activity of its molecules.
- Increased Spacing: The greater activity of the heated molecules increases the spacing between neighboring molecules.
- Reduced Density: This increased spacing reduces air density.
- Lower Pressure: The decreasing air density then lowers the pressure exerted by the air. Warm air is thus lighter (less dense) than cold air and consequently exerts less pressure.
Therefore, because warm air is less dense, it exerts less pressure, leading to a low-pressure system.
