Constant-Pressure Calorimter?

A 34.32 g stainless steel ball bearing at 117.82°C is placed in a constant-pressure calorimeter containing 120.0 mL of water at 18.44°C. If the specific heat of the ball bearing is 0.474 J/g°C, calculate the final temperature of the water. Assume the calorimeter to have negligible heat capacity.

1. Energy = (delta T)(mass)(specific heat)

2. For the ball you have the data for the right side, so solve for energy

3. Energy of the ball = energy of the water

4. Now for the water you have everything but the delta T of the water, solve for delta T and compute the final temp.
