Question

Which of the following statement is true about real gases?

• A. They show deviation from ideal behavior
• B. The molecules cause attractive forces on each other
• C. They obey gas laws at lower temperatures and high pressure
• D. Both (A) and (B)

Answer 1

The correct option is D

Both (A) and (B)

Explanation for correct option:

D. Both (A) and (B)

Real gases:

• Real gas behaves like an ideal gas at high temperature and low pressure.
• “Real gases show deviations from ideal gas law as there is the interaction between the moelcules.”
• Real gases have small attractive and repulsive forces between particles.
• The particles of real gases have a finite volume.

Explanation for incorrect options:

Real gases show deviation from ideal behavior and the molecules cause attractive forces on each other. Thus options A, B, and C are incorrect.

Hence, the correct option is D i.e. Both (A) and (B).
