It cools.
dew point
When air cools to a temperature where it can no longer hold all of its water vapor, the air has reached its dew point. This is when condensation occurs, forming clouds or fog.
When air temperature cools, the water vapor in the air may condense to form clouds or fog if the air becomes saturated with moisture. If the temperature drops further, the water vapor may further condense into liquid water droplets and fall as precipitation, such as rain or snow.
When work is done on the air to compress it, its temperature increases. This is because the compression process adds energy to the air molecules, causing them to move faster and collide more frequently, leading to an increase in temperature.

as air cools, the space it occupies becomes less. this result in an increas density
As air cools, the space it occupies becomes less. This results in an increase in density.
It expands and cools
It decreases. As air cools, mist, then clouds, then rain / snow forms... as the moisture is displaced.
dew point
it cools down
When air cools to a temperature where it can no longer hold all of its water vapor, the air has reached its dew point. This is when condensation occurs, forming clouds or fog.
When air temperature cools, the water vapor in the air may condense to form clouds or fog if the air becomes saturated with moisture. If the temperature drops further, the water vapor may further condense into liquid water droplets and fall as precipitation, such as rain or snow.
It thickens and turns into a gel
Tornados
When the air cools, water vapor may undergo condensation and turn into liquid water or ice depending on the temperature. This process forms clouds, fog, or precipitation, such as rain or snow.
