With the complete combustion of 1 kg of natural gas, 44 MJ of heat was released. What is the calorific value of the fuel?

Given:

m = 1 kilogram is the mass of natural gas;

Q = 44 MJ – the amount of heat released during the complete combustion of natural gas.

It is required to determine q (Joule / kilogram) – specific heat of combustion of the fuel.

Let’s translate the units of measurement of energy into the SI system:

Q = 44 MJ = 44 * 10 ^ 6 Joules.

Then, to determine the specific heat, you must use the following formula:

Q = q * m, from here we find that:

q = Q / m;

q = 44 * 10 ^ 6/1 = 44 * 10 ^ 6 Joule / kilogram.

Answer: the specific heat of combustion of natural gas is 44 * 106 Joule / kilogram.
