Boyles law Boyles law Boyles law shows that, at constant temperature, the product of an ideal gasspressure and volume is always constant. It was published in 1662. It can be determined experimentally using a pressure gauge and a variable volume container. It can also be derived from the kinetic theory of gases:if a container, with a fixed number of molecules inside, is reduced in volume, more molecules will hit a given area of the sides of the container per unit time, causing a greater pressure. As a mathematical equation, Boyles law is: wherePis the pressure (Pa),Vthe volume (m3) of a gas, andk1(measured in joules) is the constant from this equation—it is not the same as the constants from the other equations below. This is known as Boyles law which states: the volume of a given mass of gas is inversely proportional to its pressure, if the temperature remains constant. Mathematically this is: where k is a constant of proportionality.
