An ice cube is dropped into a glass of milk at 20°C. Which statement explains the transfer of kinetic energy (KE)?

Temperature reflects the average kinetic energy of particles. The milk at 20°C is warmer than the ice, so its particles have greater average kinetic energy. Energy transfers from the warmer milk to the colder ice until they move toward thermal equilibrium; therefore, the correct choice is “Because milk has higher KE than ice, KE is transferred from the milk to the molecules of ice.”
