A car engine whose output power is 145 hp operates at about 16 % efficiency. Assume the engine's water temperature of 79 ∘C is its cold-temperature (exhaust) reservoir and 495 ∘C is its thermal "intake" temperature (the temperature of the exploding gas-air mixture). What is the ratio of its efficiency relative to its maximum possible (Carnot) efficiency? Estimate how much power (in watts) goes into moving the car. How much heat, in joules and in kcal, is exhausted to the...
