A particular car engine operates between temperatures of 400°C(inside the cylinders of the engine) and 20°C (the temperature ofthe surroundings).
Given these two temperatures, what is the maximum possibleefficiency the car can have? (Note that actual car engineefficiencies are in the 20-25% range.)

Part (b)
A particular car engine operates between temperatures of 400°C(inside the cylinders of the engine) and 20°C (the temperature ofthe surroundings).
If the car was somehow able to operate at its maximum efficiency,determine how much heat must be obtained by burning fuel in thecar’s engine to accelerate a 1500 kg car from rest to a speed of100 km/h (neglect resistive forces). Note that a number like1.23x10^9 can be entered as 1.23e9
