Which aerostat was invented by the Montgolfier brothers in 1782?
2A hot-air balloon
1An Airship
Right answer!
A hot-air balloon is an aerostat composed of a gondola surmounted by a light envelope and whose sustentation is ensured by the force of Archimedes' thrust. The maintenance of the air temperature requires the carrying of a fuel and a burner. It is generally accepted that the hot-air balloon was invented by the Montgolfier brothers in 1782.
