The lightest volatile liquid item frequently obtained through the distillation of petroleum.
Its main hydrocarbon constituents tend to be hexane and heptane, C6H14 and C7H16, in differing proportions. It boils between 149° and 194° F. and provides off a vapor under atmospheric stress at all conditions. The vapor of gasolene is 3.05 times as heavy as atmosphere. The volatile elements distil off on storage space, unless the containing-vessels are very tight. Its calorific power is all about 18,000 B. T. U. it's much utilized in the internal-combustion motors of motor-cars and motor-boats.
a volatile combustible combination of hydrocarbons (hexane and heptane and octane etc.) derived from petroleum; mainly utilized as a fuel in internal-combustion motors
