Question

200g On this scenario a customer is served a cup of water in a dinner, and by the time she gets around to drinking it, the water has come to room temperature. What is the change in entropy of the universe for this spontaneous process? Whenever a process occurs spontaneously there is free energy available for the taking. How much work could have been extracted when the water warmed up?

Step 1

When the water comes to room temperature, it means that heat is transferred from the surroundings (room) to the water. This transfer of heat increases the entropy of the water, as its molecules become more disordered. However, it also decreases the entropy of the Show more…

On this scenario, a customer is served a cup of water in a dinner and by the time she gets around to drinking it, the water has come to room temperature. What is the change in entropy of the universe for this spontaneous process? Wherever a process occurs spontaneously, there is free energy available for the taking. How much work could have been extracted when the water warmed up?
