The specific gravity of gasoline ranges from 0.71 to 0.77, with higher densities having a greater volume fraction of aromatics. Finished marketable gasoline is traded (in Europe) with a standard reference of 0.755 kilograms per liter (6.30 lb/U.S. gal), and its price is escalated or de-escalated according to its actual density. Because of its low density, gasoline floats on water, and therefore wa… WebOs gases são moléculas ou átomos que se movimentam constantemente.
