A real gas has pressure lower than PV = nRT predicts. Which factor explains this?
A.Attractions between gas particles
B.The volume of the gas particles
C.Higher temperature
D.Perfectly elastic collisions
Explanation
Core Concept
Intermolecular attractions pull particles together as they approach the wall, weakening each collision. The measured pressure therefore falls below the ideal prediction.
Correct Answer
AAttractions between gas particles
