In the calibration step of a thermochemistry experiment, a current of 124 mA, from a 24.0 V source was allowed to flow through the electrical heater for219 s and was found to result in an increase in the temperature of the calorimeter and its contents of +1.39 K. Given that the energy supplied by an electrical circuit is the voltage multiplied by the current, multiplied by the time, what is the heat capacity of the calorimeter and its contents? A) 194 JK^-1 B) 322 JK^-1 C) 469 JK^-1 D) 731 JK^-1
