A student adds heat to 0.350 kg of pure ice at 0.0°C until it is completely melted (but still at 0.0°C). The student does this by placing the ice in a large room with a temperature of 25.0°C. Assume the temperature of the room remains a constant 25.0°C during the process. a) What is the change in entropy of the ice/water during this melting process? Show your work. b) What is the change in entropy of the environment (the large room) during this process? Show your work. c) What is the change in entropy of the entire system (ice/water + room) during this process? What does your answer tell you about the number of microstates in the system at the end of the process as compared to the beginning?
