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

Because milk has higher KE than ice, KE is transferred from the milk to the molecules of ice.

Because milk has higher KE than ice, KE is transferred from the molecules of ice to the milk.

Because ice has higher KE than milk, KE is transferred from the milk to the molecules of ice.

Because ice has higher KE than milk, KE is transferred from the molecules of ice to the milk.

Because milk has higher KE than ice, KE is transferred from the milk to the molecules of ice.

Explanation:

The best statement that expresses the transfer of kinetic energy (K. E) is that kinetic energy is transferred from the milk to the ice.

Kinetic energy is form of energy due to motion of the particles of a medium. In this regard, we are dealing with heat energy.

Heat energy is dissipated from a body at higher temperature to one at a lower temperature. Ice is at a lower temperature which is 0°C Heat will be transferred in form of thermal energy from the body at higher temperature to one with a lower temperature. This is from the milk to the molecules of ice.
