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

Question

1. Water at 40* in a swimming pool
2. A drop of water at 90*C
3. Water at 36*C in a glass
4. An iceberg at 0*C

Answer 1

The object that will have particles with the highest average kinetic energy is the drop of water at 90°C. The average kinetic energy of particles increases with temperature, so the higher the temperature, the higher the average kinetic energy.
