2. Hot air balloon uses a burner to heat up the air inside the balloon.Hot air is therefore lighter than cold air and Helium gas is filled in the balloon.Hot air is less dense than cool air; the heated air causes the balloon to rise simply because it is lighter than an equal volume of cold air. Buoyancy is an upward force that the air exerts, and it helps hot-air balloons and blimps stay in the air.

When the air inside the balloon is heated, the molecules in the air begin to move around and spread out, and the air becomes less dense. The surrounding, colder air falls beneath the hot air. This forces the warm air upward, which pushes the balloon up with it. The moving warm air creates a convection current.
