m = 100 g = 0.1 kg.
λ = 0.38 * 10 ^ 7 J / kg.
Q -?
During the combustion of gunpowder, the amount of heat Q is released, which is determined by the formula: Q = λ * m, where λ is the specific heat of combustion, m is the mass of the gunpowder that burned.
Q = 0.38 * 10 ^ 7 J / kg * 0.1 kg = 0.038 * 10 ^ 7 J = 380 kJ.
Answer: during the combustion of gunpowder, Q = 380 kJ of the amount of heat will be released.
