Answer:
A cup of boiling water.
Step-by-step explanation:
Due to their mobility, particles in a substance contain kinetic energy. The average kinetic energy of the particles increases with temperature.
Since hot water has the highest temperature of the available possibilities in this situation, it has the highest average kinetic energy. Compared to particles in icy water, warm water, or room temperature water, those in hot water are moving more quickly and possess more energy.
For instance, when hot water is compared to frozen water, the particles in the hot water are moving more quickly due to the higher temperature. The lower temperature of ice water causes the particles to move more slowly. A difference in average kinetic energy results from this difference in velocity.
