The diagrams show the movement of particles for two substances. The left image labeled X shows spaced out green balls with long movement lines behind them. The right image shows tightly cluster green balls with short movement lines behind them. 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. Substance Y has the highest temperature because it has more particles.
