How much energy is released during the complete combustion of gasoline, the volume

How much energy is released during the complete combustion of gasoline, the volume of which is 5 liters? the density of gasoline is 710?

Given:

V = 5 liters = 0.005 m ^ 3 – the volume of gasoline;

ro = 710 kg / m ^ 3 is the density of gasoline;

q = 44 * 10 ^ 6 Joule / kilogram – specific heat of combustion of gasoline.

It is required to determine how much energy Q (Joule) will be released during the complete combustion of gasoline with a volume of V.

Let’s find the mass of gasoline:

m = ro * V = 710 * 0.005 = 3.55 kilograms.

Then, during the combustion of gasoline, heat will be released, equal to:

Q = q * m = 44 * 10 ^ 6 * 3.55 = 156.2 * 10 ^ 6 Joules = 156.2 MJ.

Answer: with complete combustion of 5 liters of gasoline, an energy equal to 156.2 MJ will be released.
