Question

Give the differences between ideal and non ideal (real) gases. 

Answer 1

	Ideal gas	Real gas
1	Obeys both Boyle‟s and Charle‟s law at all T and P	Does not obey Boyle‟s and Charle‟s law at all P and T.
2	Obeys ideal gas equation PV=nRT.	Does not obey ideal gas equation PV=nRT
3	There are no intermolecular force of attraction between gas molecules.	There are weak van der Waal‟s force of attraction between gas molecules.
4	Volume of gas molecules is negligible when compared to the total volume occupied by the gas.	Volume of the gas molecules cannot be ignored when compared to the total volume occupied by the gas at high pressure.
5	Cannot be liquefied	Can be liquefied
