| m = 20 kg.
Q = 880 MJ = 880 * 10 ^ 6 J.
λ -?
The amount of heat Q, which is released during fuel combustion, is determined by the formula: Q = λ * m, where λ is the specific heat of combustion of the fuel, m is the mass of the fuel that has burned.
Let us express the specific heat of combustion of oil from the formula: λ = Q / m.
λ = 880 * 10 ^ 6 J / 20 kg = 44 * 10 ^ 6 J / kg.
Answer: the specific heat of combustion of oil is λ = 44 * 10 ^ 6 J / kg.
