There are four conditions on the basis of which the real gases differ from the ideal gases and they are as follows:
Firstly, real gases do not obey PV = nRT while the ideal gases follow it. Secondly, for real gases, volume is not zero for the temperature, To. Thirdly, real gases condense to form liquids while the idea gases do not show this behavior. Fourthly, real gases exhibit critical behavior. Therefore, on the basis of all these conditions, real gases differ from ideal gases.
