When you add cold milk and hot chocolate, they will slowly blend as the cooler liquid mixes with the warmer liquid. Eventually, the heat will be spread out evenly through the entire liquid. Which statement best explains why this happens?(1 point)

The statement that best explains why the cold milk and hot chocolate eventually blend and reach an even temperature is:

Heat always moves from areas of higher temperature to areas of lower temperature.

This statement captures the concept of heat transfer, where thermal energy moves from the hotter liquid (hot chocolate) to the cooler liquid (cold milk) until thermal equilibrium is reached.
