he 4.01 States of Matter Reading tells us that the kinetic molecular theory is a scientific model that explains the behavior of gasses at the molecular level.

What does the word 'kinetic' refer to?

a. It tells us that gas molecules move, but solid and liquid molecules don't.

b. It tells us that all molecule are in constant motion.

c. It tells us that molecules don't move.

d. It tells us that molecules have stored energy.

The correct answer is:

b. It tells us that all molecules are in constant motion.

The term "kinetic" refers to the energy of motion, and in the context of the kinetic molecular theory, it emphasizes that all states of matter (solid, liquid, and gas) involve molecular motion, with the amount of motion varying based on temperature and state.
