Question

Pressure of real gas is less than the pressure of ideal gas because:

• A. No. of collisions increases
• B. Definite shape of molecule
• C. K.E. of molecule increases
• D. Inter molecular forces

Answer 1

The correct option is D Inter molecular forces

The pressure of real gas is less than the pressure of ideal gas because Intermolecular forces of attraction are present which reduces the impact on the walls and reduce the measured observed pressure.

In the case of an ideal gas, it was considered that there is no intermolecular force of attraction.

Hence, the correct option is $\text{D}$
