Question

the closeness of particles of gas and their low speeds allow intermolecular forces to become important at certain pressures and temperatures. which best describes this statement? this is a limitation of the kinetic - molecular theory. this is a postulate of the kinetic - molecular theory. this describes ideal gas behavior using the kinetic - molecular theory. this describes ideal gas behavior without the kinetic - molecular theory.

Explanation:

The kinetic - molecular theory assumes gas particles have no intermolecular forces and are far apart. When particles are close and intermolecular forces matter at certain pressures and temperatures, it goes against the assumptions of the theory, indicating a limitation.

Answer:

This is a limitation of the kinetic - molecular theory.
