1. Ten grams of computer chips with a specific heat of 0.3 kJ/kg-K are initially at 20C. These chips are cooled by placement in 5 grams of saturated liquid R-134a at -40C. Presuming that the pressure remains constant while the chips are being cooled, determine the entropy change of (a) the chips, (b) the R-134a, and (c) the entire system. Is this process possible? Why? (Answer: 0.000841 kW/K; -0.000687 kW/K, 0.000154 kW/k)
