# A sample of hot water at temperature \(T_{\text{hot}}\)

A sample of hot water at temperature \(T_{\text{hot}}\)

- **A.** Energy transfers spontaneously from the cold water to the hot water because heat naturally flows to maximize the temperature difference within an isolated system.
- **B.** Energy transfers spontaneously from the hot water to the cold water because the total entropy of an isolated system must remain constant during any thermal process.
- **C.** Energy transfers spontaneously from the hot water to the cold water because the hot water gains entropy as thermal energy leaves it, while the cold water loses entropy.
- **D.** Energy transfers spontaneously from the hot water to the cold water because the entropy gained by the cold water is greater than the entropy lost by the hot water, increasing the total entropy of the system.
