Real gas:
1. Shows deviation from Boyle's and Charles' law at high pressure and temperature, i.e. obeys Boyle's law and Charles' law at low pressure and high temperature. $\frac{ PV }{ nRT } \neq 1$
2. Molecules are not perfectly elastic.
3. Intermolecular attraction is present, hence collision takes place with loss of kinetic energy.
4. Actual volume of individual gas molecule is significant at high pressure and low-temperature.
5. Real gases undergo liquefaction at low' temperature when cooled and compressed.
6. Gases that exist in nature like $H _2, O _2, CO _2, N _2, He$, etc. are real gases.
