The ideal gas law, PV = nRT, relates pressure, volume, moles, and temperature of a gas through the ideal gas constant R, which serves as the proportionality constant converting between the energy-dimensioned product of pressure and volume (force times distance, i.e., Joules) and the mole-Kelvin scale of amount and temperature. This belongs to the domain of chemistry, specifically gas laws within thermodynamics/physical chemistry, where temperature is understood as a measure of average energy per molecule and pressure-volume as proportional to total system energy. Determining the mass of a gas sample from PV = nRT further connects the ideal gas law to stoichiometry via molar mass, the ratio of a substance's mass to its amount in moles.
