ANSWER

D. The particles of solids have less kinetic energy than the particles of liquids or gases.

EXPLANATION

We want to identify the statement that is true about the phases of a given substance.

A gas is a state of matter that expands freely so as to fill the container which contains it. This implies that gases have no fixed shape or location.

The particles of a liquid are more closely packed than gases, implying that motion is restricted for liquids. Since kinetic energy is dependent on motion, it implies that less motion equals less kinetic energy and so liquids have lesser kinetic energy than gases.

In gases, the intermolecular forces are very weak and can be said to be negligible since the particles move freely.

As stated above, kinetic energy is dependent on motion. This means that the more movement that occurs, the more the kinetic energy. The particles of solids are more closely packed than in liquids and gases. This implies that these particles possess less kinetic energy.

Therefore, the correct option is option D.
