With the complete combustion of fuel weighing 15 kg, an energy equal to 210 MJ was released. Determine the specific heat of combustion of the fuel and its type.
Initial data: m (mass of burned fuel) = 15 kg; Q (energy released during fuel combustion) = 210 MJ = 210 * 10 ^ 6 J.
The specific heat of combustion of an unknown fuel is determined from the formula: Q = q * m, whence q = Q / m = 210 * 10 ^ 6/15 = 14 * 10 ^ 6 J / kg.
Answer: The obtained value of the specific heat of combustion corresponds to peat (solid fuel).
