How much heat does 20kg of peat give when completely burned?

To find the heat that will be given during the combustion of 20 kg of peat, we apply the formula: Q = qt * m.

Constants and variables: qt – specific heat of combustion of peat (qt = 1.4 * 10 ^ 7 J / kg); m is the mass of peat taken (m = 20 kg).

Calculation: Q = qt * m = 1.4 * 10 ^ 7 * 20 = 280 * 10 ^ 6 J (280 MJ).

Answer: Due to the complete combustion of 20 kg of peat, 280 MJ of heat will be obtained.
