William Henry was a British chemist and physician whose most important work was his study of
the solubility of gases in water under varying temperatures and pressures.
He formulated (1803) what became known as Henry's
Henry's law is a principle in physical chemistry which states that the mass of a gas
dissolved in a fixed quantity of a liquid is directly proportional to the
pressure of the gas on the liquid, at constant temperature. Thus the more
a gas is compressed, the more it is absorbed in a liquid.
