univerkov | January 5, 2021 | education

Initial data: m (mass of burnt peat) = 3.5 kg.
Reference values: q (specific heat of combustion of peat) = 14 MJ / kg = 14 * 10 ^ 6 J / kg.
The amount of heat released during the combustion of 3.5 kg of peat is determined by the formula: Q = q * m.
Let’s calculate: Q = 14 * 10 ^ 6 * 3.5 = 49 * 10 ^ 6 J or 49 MJ.
Answer: When 3.5 kilograms of peat is burned, 49 MJ of thermal energy is released.
