A hot air balloon flies because hot air inside the balloon is less dense than the cooler air outside A hot air balloon demonstrates the transfer of thermal energy, as the burner heats the air inside the balloon, causing it to become less dense and rise This temperature difference creates lift, allowing the balloon to rise and float in the air.

A hot air balloon runs on the energy stored in the heated air inside the balloon envelope
The heat is usually generated by burning propane gas in a burner located below the opening of the balloon.
Cold air or hot air Cold air typically has less force than hot air because cold air is denser and therefore heavier, making it more difficult to move Hot air is lighter and tends to. Hot air ballons use hot air
Hot air being lighter and therefore less dense than normal air allow the balloon to float. The solid would be the basket and balloon, and the tanks holding flammable gas The liquid is water vapor released by burning the gas The gases are the fuel in the tank, and the heated air in the.
In natural convection, cold air sinks because it is denser than hot air
As the cold air sinks, it displaces the hot air, which then rises This creates a continuous flow of air from cold to hot.
