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)

Question

Responses

The molecules of the two liquids form chemical bonds to spread energy.

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

Answer 1

The statement that best explains why cold milk and hot chocolate eventually blend together is:

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

This concept describes the process of thermal energy transfer, where the heat from the warmer liquid (hot chocolate) moves to the cooler liquid (cold milk) until thermal equilibrium is achieved.
