Write difference between Ideal gas & Real gas?

Open in App

Solution

Ideal Gas Real Gas
1) Ideal gas obeys all gas laws under all conditions of temperature and pressure. 1) Real gas obeys gas laws at low pressure and high temperature.
2) The volume occupied by the molecules is negligible as compared to total volume. 2) The volume occupied by molecules is not negligible as compared to total volume of gas.
3) The force of attraction among the molecules are negligible. 3) The force of attraction are not negligible at all temperatures and pressures.
4) $P V = n R T$ 4) $(P + \frac{a n^{2}}{V^{2}}) (V - n b) = n R T$
