A piece of hot metal should be cooled rapidly (quenched) to 25C, which requires removal of 1000
Question:
(1) Submerge the metal into a bath of liquid water and ice, thus melting the ice.
(2) Let saturated liquid R-22 at −20°C absorb the energy so that it becomes saturated vapor.
(3) Absorb the energy by vaporizing liquid nitrogen at 101.3 kPa pressure.
a. Calculate the change of entropy of the cooling media for each of the three cases.
b. Discuss the significance of the results.
