Problem: A 35 gram sample of copper (Csp(Cu) = 0 685 J/(g°C) is placed in a constant-pressure calorimeter containing 100 g of water that just stopped boiling. After some time the temperature of the water becomes constant at 92.3°C. What was the initial temperature of the copper block? Assume no heat is lost to the surroundings.
