Question

Distinguish between ideal gas and real gas.

Answer 1

Ideal Gas	Real Gas
If the atoms or molecules of gas do not interact with each other then it is called an ideal or perfect gas.	If the atoms or molecules of a gas interact with each other with a definite amount of intermolecular (or) interatomic force, then it is called real gas.
At a very high temperature (or) low pressure, a real gas behaves as an ideal gas, because there is no interatomic (or) Intermolecular force of attraction.	At very high temperature (or) low pressure, the interatomic (or) Intermolecular forces of attraction are weak in an ideal gas.
