What is the specific heat of combustion of aviation kerosene if, with complete combustion of 25 kg of kerosene, 1700 kJ of heat are released?
Initial data: m (mass of completely burnt aviation kerosene) = 25 g = 25 * 10 ^ -3 kg; Q (heat released during the combustion of kerosene) = 1700 kJ or 1700 * 10 ^ 3 J.
We express the specific heat of combustion of aviation kerosene from the formula: Q = q * m; q = Q / m.
Let’s calculate: q = 1700 * 10 ^ 3 / (25 * 10 ^ -3) = 68 * 10 ^ 6 J / kg = 68 MJ.
Answer: According to the calculation, the specific heat of combustion of aviation kerosene is 68 MJ.
