How can estimate the maximum height, neglecting all forms of friction, to which a car of mass 1000kg can be driven on the 1.00 gallon of fuel given that the engine cylinder temperature is 2000C and the exit temperature is 800C? Assume that an internal combustion engine runs on octane, for which the enthalpy of combustion is -5512kJ/mol and take the mass of 1 gallon of fuel as 3kg.
