A 22.4 g silver ring (cp = 234 J/kg·°C) is heated to a temperature of 77.4°C and then placed in a calorimeter containing 4.08 ✕ 10-2 kg of water at 24.0°C. The calorimeter is not perfectly insulated, however, and 0.132 J of energy is transferred to the surroundings before a final temperature is reached. What is the final temperature?
