Steam at 100C is condensed into a 54.0 g copper calorimeter cup containing 300 g of water at 27.0C. Determine the amount of steam (in g) needed for the system to reach a final temperature of 56.0C. The specific heat of copper is 387 J/(kg C). Answer in g Be sure to account for the heat energy absorbed by the calorimeter cup and the water in the cup, and the heat energy contributed by the steam. Note that the steam contributes heat energy by two processes: first, the condensation of steam into water, and second, the cooling of the associated water to the final temperature. The algebra involved is straightforward; however, since the problem has a large number of values, it is critical that you check your calculation carefully.
