A 25.5 g silver ring (cp = 234 J/kg·°C) is heated to a temperature of 84.0°C and then placed in a calorimeter containing 5.00 × 10 -2 kg of water at 24.0°C. The calorimeter is not perfectly insulated, however, and 0.140 kJ of energy is transferred to the surroundings before a final temperature is reached. What is the final temperature?
