A more accurate representation of the heating curve obtained with the equipment currently used for the experiment. Use the plot and the data to calculate the specific heat capacity of a 30 g graphite rod.
Initial temperature of rod = 100 °C; mass of H2O in calorimeter =130 g; cH2O = 4.184 °C g . (Assume the calorimeter has negligible heat capacity).
A. 0.20 J °C-1 g-1
B. 0.71 J °C-1 g-1
C. 0.66 J °C-1 g-1
D. 0.77 J °C-1 g-1
