Question

which statement is part of the kinetic molecular theory? a. gas particles are in constant motion. b. gas particles attract each other. c. gas particles lose their energy during collisions. d. gas particles stick to the walls of their container.

Explanation:

The kinetic - molecular theory states that gas particles are in constant random motion. It assumes no attractive or repulsive forces between gas particles (so B is incorrect), collisions are elastic (no energy loss, so C is incorrect), and there is no sticking to container walls as a fundamental part of the theory (so D is incorrect).

Answer:

A. Gas particles are in constant motion.
