Chemistry

An adiabatic tank contains 120 kg of liquidwater initially at 70 °C. Thewater within the tank is utilized to quench (cool) a15 kg steel block initially at300 °C. The steel block is dropped into the tank,and after some time the steel block and the water in the tank reachthermal equilibrium.

Determine the total entropy change during thequenching process.

Specific heat of steel : Csteel=0.50 kJ/kg*K.

Specific heat of water : Cwater=4.18 kJ/kg*K
