Ten grams of computer chips with a specific heat of 0.3 kJ/kg K are initially at 20°C. These chips are cooled by placement in 5 grams of saturated liquid R-134a

at -40°C. 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?
