univerkov | September 18, 2021 | education

Problem data: m (mass of burnt gunpowder) = 100 g (in SI m = 0.1 kg).

Reference values: q (specific heat of combustion of gunpowder) = 0.38 * 10 ^ 7 J / kg.

The heat released from the combustion of 100 grams of gunpowder is determined by the formula: Q = q * m.

Let’s make a calculation: Q = 0.38 * 10 ^ 7 * 0.1 = 0.38 * 10 ^ 6 J = 380 kJ.

Answer: The released heat from combustion of 100 grams of gunpowder is 380 kJ.
