A student followed the procedure in the lab manual to determine the heat capacity of the calorimeter. The student measured the temperature of 49.2 mL of room temperature water to be 20.9 °C and that of 49.4 mL of cold water as 1.8 °C. After combining the two water samples in the calorimeter the student acquired temperature as a function of time data. A plot of these data was constructed, an extrapolation to time zero was made, and the final temperature was determined to be 12.7 °C. What is the heat capacity of the calorimeter (Ccal) in units of J/°C? (Enter your answer as a number without units.)

A chemical reaction takes place inside a flask submerged in a water bath. The water bath contains 9.80kg of water at 27.4°C . During the reaction 140.kJ of heat flows out of the flask and into the bath. Calculate the new temperature of the water bath. You can assume the specific heat capacity of water under these conditions is 4.18J·g−1·K−1 . Be sure your answer has the correct number of significant digits.
