As cold water is mixed with hot water, what happens to the cold water molecules and is this identified as heat loss or heat gain?

Group of answer choices

when the two samples are mixed, energy is transferred from the cold water molecules to the hot water molecules. Resulting in a heat loss by the cold water molecules
