Which object will have particles with the highest average kinetic energy?

A. water at 40°C in a swimming pool

B. water at 37°C in a glass

C. a drop of water at 90°C

D. an iceberg at 0°C

C. a drop of water at 90°C

The average kinetic energy of particles is directly related to their temperature. According to the kinetic theory of matter, an increase in temperature leads to an increase in the average kinetic energy of particles.

Therefore, the object with the highest average kinetic energy would be the one with the highest temperature.
In this case, the correct answer would be:

C. a drop of water at 90°C
