A150-kg copper block initially at 85°c is dropped into an insulated tank which contains 75 l of water (use =1000 kg/m3 ) at 30°c. determine the final equilibrium temperature and the total entropy change for this process. since you do not know the final temperature, use specific heats evaluated at 300k as a first approximation. answers: 38.57 °c, 0.7056 kj/k.
