Explanation:
Gas balloons get their initial lift from the helium or hydrogen pumped into their envelopes.
Answer:
This heated air generates lift by way of a buoyant force. The figure below shows a typical burner. The hot air inside the envelope is less dense than the surrounding (cooler) air. This difference in density causes the hot air balloon to be lifted off the ground due to the buoyant force created by the surrounding air.
