WebFeb 2, 2011 · A perfect gas is a gas, which follows the equation of state: where p denotes the pressure (N/m 2 ); the molar volume (m 3 /mole); (= 8314 J/mole K or 8314 kJ/kmole K) the universal gas constant; and T absolute temperature, K. If both sides of the equation are divided by (the molecular mass of a given gas), the equation will be: WebThe pressure, P P, volume V V, and temperature T T of an ideal gas are related by a simple formula called the ideal gas law. The simplicity of this relationship is a big reason why we typically treat gases as ideal, unless there is a good reason to …
