Physics

Ice cubes at 0 c are poured into a glass that contains 150 g ofliquid water at 20 c. The contents of the glass are gently stirredand after short time the ice melts and the liquid cools to 0 c. Noappreciable heat exchange with the environment takes place.
a) calculate the entropy change of the universe (system plusenvironment) during the process. Cp=Cv = 4.18 kj/kgK
b)if the same process were performed reversibly, how much usefulwork would be obtained from it?

Total Entropy Change A system and surrounding are both components of the universe total which can be seen in this equation StotalSuniv Ssys Ssurr0 the system and surroundings collective represent the change in entropy The entropy change of the surroundings is driven by heat flow and the heat flow determines the sign of Ssurr Therefore if we had an exothermic reactions with a constant temperature the system would cause heat to See Answer
