Boyle's law (boilz)
The principle that at a constant temperature the volume of a confined ideal gas varies inversely with its pressure.
The principle that the volume of a given mass of an ideal gas is inversely proportional to its pressure, as long as temperature remains constant. Boyle's law is a subcase of the ideal gas law. Compare Charles's law.
