With the complete combustion of 15 kg of anthracite, 435 MJ of energy was released.

With the complete combustion of 15 kg of anthracite, 435 MJ of energy was released. Determine the specific heat of combustion of anthracite.

Given:

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.
