Frequently Asked Questions on Balloon Rides - Hot Air Balloon
Hot air rises. The envelope traps a large bubble of hot air. When the air in the envelope is heated by the burner, the balloon will rise. When the air in the envelope is allowed to cool or if the hot air is "vented" (allowed to escape) from the top of the envelope, the balloon will descend. An altimeter (to measure altitude), a rate-of-climb meter, and an envelope temperature gauge are the only instruments used in the balloon.

Balloon (aeronautics) - Wikipedia, the free encyclopedia
In aeronautics, a balloon is an unpowered aerostat, which remains aloft or floats due to its buoyancy. A balloon may be free, moving with the wind, or tethered to a fixed point. It is distinct from an airship, which is a powered aerostat that can propel itself through the air in a controlled manner.
