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)

Responses

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

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

The liquids attract each other because the densities of the liquids are the same.

Cold liquids rise and hot liquids sink making the liquids mix.

The best explanation for why cold milk and hot chocolate eventually blend and reach a uniform temperature is:

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

This statement correctly describes the fundamental principle of heat transfer, where thermal energy flows from the hotter liquid (hot chocolate) to the cooler liquid (cold milk) until thermal equilibrium is reached.
