Suppose that an internal combustion engine runs on octane, for which the enthalpy of combustion is -5512 kJ mol ^-1 and take the mass of 1 gallon of fuel as 3 kg. What is the maximum height, neglecting all forms of friction, to which a car of mass 1000 kg an be driven on 1.00 gallon of fuel given that the engine cylinder temperature is 2000 degrees celsius and the exit temp is 800 degrees celsius.
