Σελίδα 173 - ... gas may be expelled from a liquid, viz. : 1. When the liquid is supersaturated, the excess gas is expelled. 2. By heating the liquid, when some of the gas is expelled due to an increase in its volume. 3. By pressure reduction, as in the Elmore vacuum process, where, according to the law of Henry,14 "the amount of gas dissolved by a liquid is proportional to the pressure to which the gas is subjected.
