A 140.0-g sample of water at 25.0°C is mixed with 126.1 g of a certain metal at 100.0°C. After thermal equilibrium is established, the (final) temperature of the mixture is 29.6°C. What is the specific heat capacity of the metal, assuming it is constant over the temperature range concerned?
Having just invented a new type of calorimeter, Dr. Cox needs to determine the heat capacity of the calorimeter. She carries out the following experiment to do this: Her empty calorimeter is at a temperature of 25.0ºC. She adds 32.502 grams of water at a temperature of 72.5ºC to the empty calorimeter and the final temperature of the calorimeter and the water is 39.5ºC. Based on this experiment, what is the heat capacity of her calorimeter assuming units of J/ºC? Enter your answer with at least 3 sig figs.
