How much heat does 20kg of peat give when completely burned?
October 4, 2021 | education
| 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.
