Assuming that a typical car engine operates at an efficiency of 26% and one gallon of gasoline releases approximately 150 x 106 J of heat when it is burned, determine:

(i) Of the energy available in a gallon of gas, how much energy can be used to do useful work in moving the automobile?

(ii) How much heat per gallon is released to the environment in the exhaust gases and via the radiator?

(iii) Would you expect the efficiency of the engine to be slightly greater on a very hot day or on a cold day? Explain your answer.
