Cold air masses have molecules that are densely packed and close together, unlike warm air.
heat rises
The hot and dry air mass is most likely to move in the direction where lower pressure systems exist. This typically means that it will move towards areas with cooler temperatures or where moist air masses are located.
Hot air generally rises because it is less dense than cold air. As air heats up, its molecules move faster and spread out, making the air less dense and causing it to rise above cooler, denser air. This movement creates convection currents, where hot air rises and cooler air sinks, leading to the circulation of air in the atmosphere.

If a cool air mass comes in on a hot day, and if there is enough moisture, you can generally expect showers and thunderstorms.
Hot air rises. That is how a hot air balloon works.
Hot air. Because it always rises above cold
Hot air is lighter than cold air, so it rises up. Ex. A hot air balloon rises up because we heat the air and it goes up.
Hot air rises and cold air falls.
