Answer published by the source. Consult the official source to check your work against its answer.
question
A 34 kg steel casting at a temperature of 427°C is quenched in136 kg of oil initially at 21°C. Assuming no heat losses and thesteel casting and oil to have constant specific heats of 0.5024and2.5121 kJ/kg-°K respectively, determine the - changein entropy for a system consisting of the oil and casting.
