What is the Universal Gas Law?

The Universal Gas Law (also called the Universal Gas Constant or the Perfect Gas Law), is a chemical law that can also be looked at mathematically. It is represented by the equation PV = nRT, in which P is pressure, V is volume, n is the number of moles of gas, R is the gas constant, and T is the temperature in Kelvin. (For more about the Kelvin temperature scale, see “Mathematics throughout History.”)
