*''P'' is the [[pressure]] of gas;
*<math>P</math> is the [[pressure]] of gas;
*''V'' the [[volume]] the gas occupies;
*<math>V</math> the [[volume]] the gas occupies;
*''T'' the absolute [[temperature]] (meaning it must be in [[Kelvin]] or [[Rankine]]);
*<math>T</math> the absolute [[temperature]] (meaning it must be in [[Kelvin]] or [[Rankine]]);
*''n'' is the number of [[Mole (chemistry)|moles]] of the gas occupying the volume V;
*<math>n</math> is the number of [[Mole (chemistry)|moles]] of the gas;
*''R'' is the ideal gas constant.
*<math>R</math> is the ideal gas constant.
It can also be expressed in terms of the number of [[molecules]], <math>N</math> and the Boltzmann constant, <math>k_B</math> as:
:<math>PV = N k_B T</math>
The ideal gas constant can be expressed in any number of units, but the most common representations are <math>0.0821\,L \cdot atm \cdot mole^{-1} \cdot K^{-1}</math> or <math>8.314\,J \cdot mole^{-1} \cdot K^{-1}</math>
