Question

according to the law of entropy, when hot and cold objects meet, heat flows from hotter to colder. what would be the end result of mixing hot water and cold water? all the water would reach an equilibrium temperature and heat would stop flowing. the cold water would continue to heat up. the warm water would continue to cool down. the two volumes of water would balance out but the temperature of the two would keep fluctuating.

Explanation:

Per the law of entropy, heat flows from hotter to colder objects until a uniform, stable temperature (thermal equilibrium) is achieved, at which point heat transfer stops. The other options are incorrect because the cold water will not keep heating indefinitely, the warm water will not keep cooling indefinitely, and temperatures will not fluctuate once equilibrium is reached.

Answer:

All the water would reach an equilibrium temperature and heat would stop flowing.
