A stainless-steel bar is heat up to 1400K and cooldown to improve the hardness of the metal is removed from an furnace and cool down by immersing it in 15 kg of water at 27C. appropriate constant specific heat value for the water is C = 4.2 kJ/kg- K, and for the meta consider Cm=0.42 kJ/kg K. Heat transfer from the tank contents can be neglected. Determine (a) Final temperature of the system in K, and (b) irreversibility of the system.
