Question
When cold milk is added to hot tea, the liquids slowly blend together as the cooler liquid mixes with the warmer liquid. Eventually, the heat will be distributed evenly through the entire liquid. Which best explains the reason the heat spreads through the liquid?
Group of answer choices
Cold liquids rise and hot liquids sink, creating a mixture of liquids.
The densities of the liquids are similar, so they attract each other.
The molecules of the two liquids create chemical bonds that help spread energy.
Heat always moves from areas of higher temperature to areas of lower temperature.

The statement that best explains the reason the heat spreads through the liquid is:
**Heat always moves from areas of higher temperature to areas of lower temperature.**
This principle is based on the second law of thermodynamics and explains how heat energy transfers until thermal equilibrium is reached. In this case, the heat from the hot tea will transfer to the colder milk until the temperatures equalize.
