Question

which onr does not happend whent air is heated​

Answer 1

Answer:

Answer. When air is heated it either increases in volume, increases in pressure or both, depending on the conditions. Air is composed of several different gases, most notably nitrogen, oxygen and carbon dioxide, but the particular gas involved does not matter.

Answer 2

As air warms up, the molecules start to vibrate and bump into each other, increasing the space around each molecule. Because each molecule uses more space for motion, the airexpands and becomes less dense (lighter). ... The opposite effect happens when air cools.
