When 50 g of fuel is burned, an energy of 1.5 MJ is released. Determine the specific heat of combustion of this fuel.
| August 10, 2021 | education
Initial data: m (mass of the burned fuel) = 50 g (in SI m = 0.05 kg); Q (released thermal energy) = 1.5 MJ = 1.5 * 10 ^ 6 J.
The specific heat of combustion of the fuel taken can be calculated by the formula: q = Q / m = 1.5 * 10 ^ 6 / 0.05 = 30 * 10 ^ 6 J / kg (30 MJ / kg).
Answer: The burned fuel has a specific heat of combustion of 30 MJ / kg.
