Which of the three phases of matter (solid, liquid, or gas) has particles moving at the highest average velocity?

Question

Quizplus · Accepted Answer

In a gas, the particles have the highest average velocity because they have the most kinetic energy and are able to move freely throughout the container in which they are held. In solids, the particles are tightly packed and their movement is limited, while in liquids, the particles have more freedom of movement than solids but are still relatively close together.
