What is the change in entropy of a system consisting of one, Ask an Expert

Academics

1. How much heat does one mole of water release when its temperature is reversibly reduced from 350 K to 250 K at atmospheric pressure? You may assume that the heat capacities take constant values Cpl= 75.3 JK-1 and Cps = 36.8 JK-1. In addition ΔHfus = 6004 J at Tfus = 273 K. What are the enthalpy and entropy changes for the water?

2. What is the change in entropy of a system consisting of one mole of ideal gas when it is expanded isothermally and reversibly from a pressure of 6 bar to 2 bar at 275 K? What is the change of entropy of the surroundings?
