Short Answer

0.45 kg of a metal at 90.°C is added to 0.40 kg of water at 20.0°C.
(a) If the final temperature of the mixture is 26.°C, what is the specific heat of the metal?
(b) If the water container has a significant heat capacity, will this increase or decrease the metal specific heat determined in part (a) given the same data?
