In an 1802 paper, scientist Joseph Louis Gay-Lussac, who we shall have more to say about shortly, credited Jacques
Charles (1746-1823),Figure14.6, with what is now known asCharles’s Law. According to Charles’s Law, if the
pressure of a gas is kept constant, the volumeVof a gas varies directly with the absolute temperatureT(expressed,
as you may recall, in Kelvins),V∝TFigure14.7. Close to absolute zero, all gases will liquefy. The graph in
Figure14.7 is therefore extrapolated for temperatures close to absolute zero. We note that experimentally reducing
the temperature of any substance to zeroKis not possible.
