3. In this experiment, we have used 1.0 x 1.01 J/°C for the heat capacity of the coffee-cup calorimeter. Let us verify this number through the following experiment using only hot and cold water. Experimental procedure: Place 50 mL of water at 20.0 °C in the coffee cup calorimeter. i. ii. Add 50 mL of hot water at 98.0 °C to the calorimeter holding the cold water. ii. The Trof 58.0 °C was obtained through the temperature-time graph. Calculate the specific heat of the coffee cup calorimeter. Remember that the heat lost by the hot water was gained by the cold water as well as the calorimeter.

9.104 An engineer is using sodium metal as a cooling agent in a design because it has useful thermal properties. Looting up the heat capacity, the engineer finds a value of 28.2 J mol-l °C-l. Carelessly, he wrote this number down without units. As a result, it was later taken as specific heat. (a) What would he the difference between these two values? (b) Would the engineer overestimate the ability of sodium to remove heat from the system or underestimate it because of this error? Be sure to explain your reasoning.
