The low average density of Jupiter (about 1300 kg/m³ compared with that of water, 1000 kg/m³) indicates that this planet is composed mainly of A) hydrogen and helium in gaseous form only because low temperatures and great pressures are needed to liquefy these gases. B) water, compressed somewhat by gravity, maybe in the form of ice. C) methane, ammonia, and water, from spectroscopic observation of its atmosphere. D) hydrogen, in liquid or gaseous form.
