This is College Physics Answers with Shaun Dychko. So an equal mass of steam at a hundred degrees Celsius and ice at zero degrees Celsius are in contact, and they both end up as liquid at the same temperature. So the steam has a reduction in its entropy because it goes from a highly disordered gas with pollen particles that are separated and moving in very different directions, to a increased order liquid. And, whereas the ice has an increase in its entropy because it's become more disordered and loss in order. So an increase in disorder, which is a loss in order. So, we have a loss and a gain, and a gain and a loss. So, the answer is C.
