PERFECT GAS EQUATION

Perfect gas equation is true for imaginary perfect gas, that is, the gas, in which

• there no attractive forces between molecules, and
• the volume occupied by molecules is negligible comparing with the total volume of the gas.

The equation takes the form: pV = nRT, where
p - is gas pressure,
V - is the volume occupied by the given amount of moles of the gas,
n - is the amount of moles,
R - is the universal gas constant,
T - is the absolute temperature

With regard to real, imperfect gases, this equation is not exact. Real gas equation must take into account high density of molecules and electric interacting forces between them.
