How do you calculate the energy released per gram of food?
Energy can be calculated using the formula: Q = mc ∆T. In the formula, Q = the energy in joules or calories, m = the mass in grams, c = specific heat and ∆T = the change in temperature which is the final temperature minus the initial temperature. The specific heat for water = 1 calorie/gram °C.
