When air expands or contracts type of temperature change it experience?

Answer 1

When temperature rises, air expands and gets lighter. When temperature falls, air compresses and gets heavier. One of the rules about air temperature is that warmer air rises and cooler air falls.

Answer 2

When any gas, such as air compresses it gets warmer. This is why when you see the weatherman say there is a high pressure system moving in, more than likely, the temps are going up as well.

This is why valleys tend to be warmer than the area around them. There is more pressure on the air, hence raising it's temperature ie. Death Valley.

Now on the other hand, if you have ever taken a can on compressed air such as the stuff to keep keyboards clean, and held the spray button down long enough, the can will almost get too cold to hold. This is the result of pressure going down.

It all works at the molecular level. This is the basic principle that air conditioners and refrigerators work.

Answer 3

Air inside a container (for example a ballon) expands when the temperature of the air increases. This is because the increase in temperature causes the air partials to have a greater energy, meaning they move with a greater velocity and as such exert more force on the walls of the container causing the container to expand. The opposite happens if temperature is decreased

Answer 4

When air expands, it cools down as it loses energy and temperature drops. When air contracts, it heats up as it compresses and gains energy, causing temperature to increase.
