Question

Which statement describes a limitation of the kinetic-molecular theory for a gas?
The theory assumes that particles do not experience intermolecular forces.
The theory states that pressure is inversely proportional to volume.
The theory assumes that particles are in random and continuous motion.
The theory states that pressure increases with temperature.

Answer 1

"The theory assumes that particles do not experience intermolecular forces."

Explanation: That assumption is what makes the kinetic-molecular theory an idealized model. Real gases do have intermolecular attractions and finite particle volumes, so the theory fails at high pressures and low temperatures where real-gas deviations (condensation, nonideal P-V-T behavior) become significant.
