<span>The answer to this question would be: (3) The ice cube gains heat energy and the water loses heat energy.
Based on the law of conservation of energy, the energy in an isolated system should be constant. If something receives energy, other must be losing energy. The option 1 and 2 definitely false because the total energy is not constant.
In this case, the ice should have lower heat energy, so the ice should be the one who receives energy from the water</span>
