Problem data: m (mass of powder taken) = 10 g (in SI system m = 0.01 kg).
Reference values: q (specific heat of combustion of gunpowder) = 3.8 MJ / kg = 3.8 * 10 ^ 6 J / kg.
The heat released during the combustion of 10 g of gunpowder is calculated by the formula: Q = q * m.
Let’s perform the calculation: Q = 3.8 * 10 ^ 6 * 0.01 = 38 * 10 ^ 3 J (38 kJ).
Answer: With complete combustion of 10 g of gunpowder, 38 kJ of heat should be released.
