Initial data: m (mass of burned kerosene) = 200 g (0.2 kg); Q (thermal energy released during combustion of a given mass of kerosene) = 9200 kJ (9200 * 10 ^ 3 J).
The specific heat of combustion of kerosene is determined by the formula: λ = Q / m.
Calculation: λ = 9200 * 10 ^ 3 / 0.2 = 46,000 * 10 ^ 3 J / kg = 46 MJ / kg.
Answer: According to the calculation, the specific heat of combustion of kerosene is 46 MJ / kg.
