With the complete combustion of 15 kg of anthracite, 435 MJ of energy was released. Determine the specific heat of combustion of anthracite.
m = 15 kilograms is the mass of anthracite;
Q = 435 MJ = 435 * 10 ^ 6 Joules – the energy released during the complete combustion of anthracite.
It is required to determine q (J / kg) – specific heat of combustion of anthracite.
q = Q / m = 435 * 10 ^ 6/15 = 29 * 10 ^ 6 J / kg.
Answer: the specific heat of combustion of anthracite is 29 * 10 ^ 6 J / kg.
