An aluminum calorimeter can (specific heat equal to 900 J/kg•K) with mass 0.080 kg contains 0.380 kg ofwater (specific heat equal to 4190 J/ kg• K) in thermal equilibrium at atmospheric pressure. A 0.120 kg bar ofcopper (specific heat 387 J/ kg• K) at 300°C is dropped into the calorimeter can. The initial length (the lengthbefore being dropped in the can) of the copper bar is 5.000 cm, and its coefficient of linear expansion is 1.7 x10-5 1/K. The length of the copper bar after it reaches thermal equilibrium with the water and the aluminumcan is 4.977 cm. What is the initial temperature of the aluminum calorimeter can and the water? Assume thatno heat is lost to the surroundings.
