A balloon filled with hydrogen gas also releases heat when lit on fire. Due to differences in energy density, the crystallization of sodium acetate releases more heat per mole than the hydrogen gas ...

De Rozier's experimental system consists of a hydrogen balloon and a hot air balloon tied together. Tragically, the craft explodes half an hour after takeoff. This double balloon helium/hot air ...
