The formula by which the amount of heat released during combustion is calculated looks like this – Q = qm (Q is the amount of heat, q is the specific heat of combustion, m is the mass) We know the mass – 50 kg, the value of standard fuel in different sources may vary. Let’s take the value that Wikipedia suggests – 15 MJ / kg. This is 15,000,000 J / kg.
Multiplying, we get 750 MJ or 750,000,000 J. This will be the answer.
