Question:

10-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?
