The air particles would get denser and the air would sink. If you cool it enough the water vapor in the air might freeze.
pressure decreses
Cool, moist, heavy air replaces rising hot air
When warm air rises it continues to rise until it starts to cool down. Once it starts to cool down it begins to sink allowing more warm air to replace it. This is called convection.
This is due to the Cold Front because cooler, denser air wedges underneath the less-dense warm air.
No. Dense air is cool air.
What do you think happens when some air heats up and other air is cool?
The air becomes cool and fresh.
Condensation
The cool air will sink and the warm air will rise.
When you heat air, the air pressure rises and the particles expand.
nothing
they leave cool air
Warm air rises, and cool air sinks.
The furnance is not coming on.
pressure decreses
hi
It gets colder. And the energy increases so the particles move further apart.
