In preparation for a study of the metabolism of an organism, a small, sealed calorimeter was prepared. In the initial phase of the experiment, a current of 20.2 mA from a 15.8 V source was passed for 180.4 s through a heater inside the calorimeter. What is the change in internal energy of the calorimeter? J. 3 sig. number.
