Yes, warm air expands and rises, while cold air contracts and sinks. It could happen that a low cold air stream is forced to rise when coming up against a high mountain range. Though, once over the range, the cold air tends to cling to the far side of the range as it sinks into the bottom of the valleys on the other side.

As warm air rises it becomes cooler and the relative humidity of the air mass rises. If the relative humidity exceeds 100% water precipitates out.
As cool air sinks the air mass becomes warmer and dryer.
Both these reactions relate to the relationship PV=nRT.

The warmer fluids is less dense, and also the kinetic energy of the molecules increases.

What happens to air when it warm?

It's density decreases, so will rise (or float) above surrounding cooler air.


Warm air rises because of its?

the warm air rises because of its Kinetic energy !


How does uneven heating of earths surface results in convection currents?

Where the air is over a parts of the Earth's Surface that is warm, the air warms. Warm air rises and as it rises it is replaced by cooler air that is sucked in from parts of the Earth's surface which are comparatively cooler. This movement causes a cyclic circulation of the air called win and weather.

What happens to air as a stove heats it?

The air expands as it is heated this is due to the increased activity of the molecules composing the air. It also rises as its density is reduced compared to the cooler air in the room. The pressure of the warm air remains the same as that of the cooler air.


What happens to the air in the surroundings as warm as rises?

It gets warmer.

Warm air above the land rises and is replaced by cooler air from the water, causing a convection current. Just got this from apex!
