Question

At higher pressure, which one of the following is correct about volume of the gases?

• A. $V_{real}>V_{ideal}$
• B. $V_{real}<V_{ideal}$
• C. $V_{real}=V_{ideal}$
• D. None of these

Answer 1

The correct option is A $V_{real}>V_{ideal}$

The kinetic theory assumes that gas particles occupy a negligible fraction of the total volume of the gas. As a result, real gases are not as compressible at high pressures as an ideal gas because we can't ignore the volume of the gas molecules. The volume of a real gas is therefore larger than expected from the ideal gas at high pressures.
