| What amount of heat will be released during the complete combustion of 200 kg of coal, if the specific heat of combustion of this fuel is 30 MJ / kg?
m = 200 kilograms is the mass of coal;
q = 30 MJ / kg = 30 * 10 ^ 6 J / kg – specific heat of combustion of a stone corner.
It is required to determine Q (Joule) – the amount of heat that will be released during the complete combustion of coal.
Q = m * q = 200 * 30 * 10 ^ 6 = 6000 * 10 ^ 6 = 6 * 10 ^ 9 Joules.
Answer: with the complete combustion of coal, thermal energy will be released, equal to 6 * 10 ^ 9 Joules.
