Gases deviate from ideal behavior at high pressure.Which of the following is correct for non-ideality:
Correct answer: D. At high pressure, the inter-molecular attractions become significant
- A. At high pressure,the gas molecules move in one direction only
- B. At high pressure,the collisions between the gas molecules are increased manifold
- C. At high pressure, the volume of the gas becomes insignificant
- D. At high pressure, the inter-molecular attractions become significant
Explanation
At high pressure, gas molecules are crowded, so their finite size and intermolecular attractions cause deviation from ideal behavior. Among these, intermolecular attractions reduce the pressure, making real gases deviate from the ideal gas law

About Gases
Gas behaviour is explained through the kinetic molecular theory and the relationships among pressure, volume and temperature. Work includes STP, Boyle's and Charles's laws, absolute zero, the ideal gas equation, and the distinction between ideal and real gases, especially the effects of intermolecular forces and molecular volume.
