KnowraHot air balloonLinked fromLinked fromThe 12 pages that link to Hot air balloon, each with the reason it gives.All 12Broader topic 6Related 1Narrower topic 1Compared with 4BuoyancyBroader topic: The surrounding air supplies buoyant force when the balloon displaces heavier air.Archimedes' principleRelated: The same displaced-fluid principle applies to gases as well as liquids.BallooningBroader topic: Heating the envelope's air lowers its density and produces lift.Montgolfier brothersBroader topic: The brothers’ defining invention used heated air to lift a large fabric envelope.Charles's lawBroader topic: Heating the enclosed air expands it and lowers its density at roughly ambient pressure.Lighter-than-air aircraftCompared with: Unlike a powered airship, it generally travels with the wind rather than steering through it.Gas balloonCompared with: It produces lift by temperature difference, whereas a gas balloon uses a separate low-density gas.AerostaticsBroader topic: Heating air provides lift without requiring a separate lifting gas.AerostatBroader topic: It uses heated air rather than a separate lifting gas.BlimpCompared with: It uses heated air for lift, whereas a blimp relies on lifting gas and has propulsion.Sky lanternNarrower topic: The lantern uses the same buoyancy principle on a smaller, untethered scale.Sophie BlanchardCompared with: It provides a non-hydrogen alternative to the gas balloons associated with Blanchard.
