Question

the portable source of heat energy stored under pressure in tanks 1 propne 2 petroleum 3 nitrogen dioxide​

Answer 1

Answer:

Propane (/ˈproʊpeɪn/) is a three-carbon alkane with the molecular formula C3H8. It is a gas at standard temperature and pressure, but compressible to a transportable liquid. A by-product of natural gas processing and petroleum refining, it is commonly used as a fuel in domestic and industrial applications and in low-emissions public transportation. Discovered in 1857 by the French chemist Marcellin Berthelot, it became commercially available in the US by 1911. Propane is one of a group of liquefied petroleum gases (LP gases). The others include butane, propylene, butadiene, butylene, isobutylene, and mixtures thereof. Propane has a lower energy density but burns more cleanly than gasoline and coal.
