As air heats it becomes less dense, when it cools it becomes denser.
Air pressure
When air cools down, its molecules lose kinetic energy and move closer together, causing the air to become denser. This increase in density can lead to a decrease in air pressure, and may also result in the condensation of water vapor in the air, leading to the formation of clouds and eventually precipitation.
Wind is produced because land heats up and cools down quickly. As the land heats up, air near the surface also heats up and rises. This creates an area of low pressure, causing cooler air from surrounding areas to flow in to fill the void, resulting in wind.
Air at Earth's surface is much cooler than lava is, the lava will start to transfer heat to the air on contact. The air heats up and the lava cools down.
Cool, dense air tends to sink because it is heavier than the surrounding warmer air. As air cools, its molecules lose energy and come closer together, increasing its density. This process contributes to atmospheric circulation, where cooler air descends, while warmer air rises.
As air heats up, its density decreases, because the air molecules move further apart due to increased kinetic energy. Conversely, as air cools down, its density increases, as the air molecules move closer together due to decreased kinetic energy.

No. Lava heats up the air. In turn, the air cools the lava.
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.
Air conditioner. One heats the interior of the house; the other cools it.

During the journey, the tyre heats up and heats the air inside the tyre. The air then slightly increases in pressure. After the journey, the tyre cools down and the air cools down too, restoring the original pressure. It is best to inflate tyres when they are warm so the pressure is correct when they are running.
Air doesn't expand when it cools it contracts. any easy way to prove this point is to blow up a balloon put it in the fridge and leave it there for a while it will become smaller take it out of the fridge and it will get bigger again. Air expands as it heats and contracts as it cools.
