In a heat-treating process, a 1-kg metal part, initially at 1075 k, is quenched in a tank containing 100 kg of water, initially at 295 k. there is negligible heat transfer between the contents of the tank and their surroundings. the metal part and water can be modeled as incompressible with specific heats 0.5 kj/kg-k and 4.2 kj/kg-k, respectively. determine (a) the final equilibrium temperature after quenching, in k, and (b) the amount of entropy produced within the tank, in kj/k
