Unformatted text preview: SP26: A solid object of AISI 302 steel at a temperature of 850 C is quenched in mineral oil at a temperature of 25 C. The mass of the solid steel object is 8 kg. The specific heat and density of the oil are 1,950 kJ/kgK and 890 kg/m 3 , respectively. The oil is contained in a wellinsulated cylindrical tank that has a diameter of 1 m and a height of 1 m. (a) What is the change in the entropy (kJ/K) of the steel? (b) Determine the change in entropy (kJ/K) of the oil. (c) What is the total entropy change (kJ/K) for the system comprising of steel and oil?...
