Question

Which object will have particles with the highest average kinetic energy?
Options are
Water at 40°c in a swimming pool
An iceberg at 0°c
A drop of water at 90°c
Water at 37°c in a glass

Answer 1

A drop of water at 90°c will have particles with the highest average kinetic energy. This is because temperature is a measure of the average kinetic energy of the particles in a substance, and the higher the temperature, the higher the average kinetic energy of the particles.
