Who made volume and pressure correction to explain deviation of gases from ideal behaviour ?
Correct answer: D. Vander waal
- A. Clausius
- B. Boltzman
- C. Charles
- D. Vander waal
Explanation
Van der Waals introduced corrections for both intermolecular attraction and the finite volume of gas molecules, which explain deviations from ideal behaviour. The likely alternative is Clausius, who contributed to kinetic theory and gas equations but did not give the standard two-term volume and pressure correction named here.

About Real and Ideal Gases
An ideal gas is modelled as particles with negligible volume and no intermolecular attraction, obeying Boyle's, Charles's and Avogadro's laws through PV = nRT. Real gases deviate from this behaviour, especially at high pressure and low temperature, because particle volume and attractive forces matter; the van der Waals equation explains these corrections.
