With complete combustion of 100 g of fuel, 11 MJ of heat is released. Determine the specific heat of combustion of the fuel.
To calculate the specific heat of combustion of the taken fuel, we apply the formula: Q = qx * m and qx = Q / m.
Values of variables: Q – released heat (Q = 11 MJ = 11 * 10 ^ 6 J); m is the mass of the fuel taken (m = 100 g; in the SI system m = 0.1 kg).
Calculation: qx = Q / m = 11 * 10 ^ 6 / 0.1 = 110 * 10 ^ 6 J / kg = 110 MJ / kg.
Answer: The taken fuel, according to the calculation, has a specific heat of combustion of 110 MJ / kg.
