Hot air is less dense (lighter) than colder air, so warmer air will naturally rise above the cooler air.
Light a candle and observe the smoke. It will be going up, as opposed to sinking down.

As air (unconfined), is heated its volume increases, and its density decreases. That makes it lighter (per volume) than it was. Warm air will rise above colder air, and in essence, float on top of the colder air.
hot air rises.
Temperature decreases with altitude due to the adiabatic lapse rate, where the atmosphere cools as it expands with elevation. This principle applies in mountains where the air rises, expands, and cools, resulting in lower temperatures at higher altitudes.
Hot air rises. As the air in the hot air balloon is made hotter than the surrounding air it rises.

Hot air rises.
As a balloon rises from the ground to the air, the air density inside the balloon decreases. This is because air density decreases with altitude due to the decrease in atmospheric pressure. The air inside the balloon expands as it rises, causing it to become less dense.
hot air rises because it is less dense than cold air..this occurs by the process of convection
technically hot air does not really rise it is the cold air that sinks below it because it is more dense.
Hot air rises. That is how a hot air balloon works.
