(a) What is the hot reservoir temperature (in degrees C) of a Carnot engine that has an efficiency of 42.5% and a cold reservoir temperature of 32.5°C ? °C (b) What must the hot reservoir temperature (in degrees C) be for a real heat engine that achieves 0.730 of the maximum efficiency, but still has an efficiency of 42.5% (and a cold reservoir at 32.5°C )? °C (c) Does your answer imply practical limits to the efficiency of car gasoline engines?
