What is the difference between the REAL and IDEAL GAS? GIVE EXAMPLE

2
Real Gas Ideal Gas
Has a definite volume No definite volume
Has a definite mass Has no definite mass
Follow the gas equation: P + a/V2) (V – b) = nRT Follows ideal gas equation: pV=nRT
Volume of the molecules of a real gas is non-zero Volume of the molecules of an ideal gas is zero
Possess both kinetic and potential energy Posess only kinetic energy
Example- Nitrogen, Oxygen, Carbon dioxide Ideal gases do not exist
