A typical automobile engine works with a cylinder temp of 2000 degrees C and an exit temp of 800 degrees C. A typical ethanol fuel (molar mass 46.07 g/mol) has an enthalpy of combustion of -1364 kJ/mol and 1 dm^3 has a mass of 0.77kg. Calculate the maximum amout of work that could be performed by the combustion of 10dm^3 of fuel.
