Results and Discussion : Part 1 The average heat capacity of a calorimeter was calculated by pouring 50mL of hot water into the calorimeter that contained 50mL of cold water. Five trials were performed. The data and calculated results were put into a table (Table 1). Table 1: Heat Capacity of a Calorimeter Data and Results Trial Number 1 2 3 4 5 Mass 100mLbeaker (g) 123.64 123.71 123.71 123.86 123.79 With cold H2O (g) 172.37 168.14 170.56 166.08 161.73 Mass 50mLbeaker (g) 52.59 52.49 52.52 52.51 52.58 With hot H2O (g) 97.98 97.62 97.08 101.44 96.42 Temp hot water (C) 32.0 28.6 34.0 27.7 31.2 Temp cold water (C) 22.9 22.9 22.9 22.7 22.8 Final Temp (C) 27.1 26.1 28.3 26.1 27.0 Heat Capacity Calculated (J/C) 18.54 38.3 0.77 80.32 24.6 The Calorimeter’s Heat Capacity (C cal ) was calculated using the following formula: C(cal) = [(mass cold H2O)( s H2O )( T cold) + (mass hot H2O)(S H2O )( T hot)] / ( T cold) For example, the calculation for Trial #1 was as follows:
