For classes familar with the equation q = m × C × Δ T, where q is the heat energy, m the mass of water heated, C the specific heat of water (4.2 J g –1 deg –1) and Δ T the temperature rise, this can be used to calculate the energy (in J) absorbed by the water each time. Dividing this by the mass of foodstuff burnt gives the heat energy
