The amount of heat released during the combustion of 10 kg of fuel was 10 x 106 J. What is the specific heat of combustion of this fuel?
Initial data: m (mass of burned fuel) = 10 kg; Q (released amount of heat) = 10 * 10 ^ 6 J.
The specific heat of combustion of the initial fuel can be expressed from the formula: Q = q * m, whence q = Q / m.
Let’s calculate: q = 10 * 10 ^ 6/10 = 1 * 10 ^ 6 J / kg or 1 MJ / kg.
Answer: D) The specific heat of combustion of the initial fuel is 1 * 10 ^ 6 J / kg.
