Temperature and Thermal Energy

The diagrams show the movement of particles for two substances. Which best compares the temperatures of the substances?

• Substance X has the highest temperature because its particles have more kinetic energy.

• Substance X has the highest temperature because it has fewer particles.

• Substance Y has the highest temperature because its particles have more kinetic energy.
