In an experiment to determine the calorific value of a food, a sample of the food was burned in an oxygen atmosphere and the temperature rose by 2.89 °c. When a current of 1.27 A from a 12.5 V source flowed through the samecalorimeter for 157 s. the temperature rose by 3.88 °c. What energy is released as heat by the combustion?
