50.0 g of warm water is added to 50.0 g of cold water in a Styrofoam calorimeter. The initial temperature of warm water and cold water are 35.0 oC and 21.0 oC, respectively, and the final temperature after mixing is 27.5oC. (a) Calculate heat gained by the cold water and the amount of heat lost by warm water. (b) Assuming the temperature change for the calorimeter is the same as that of cold water, calculate the heat capacity of calorimeter. The specific heat of water is 4.184 J/g.oC.
