Problem 43P
CE A Carnot engine operates between a hot reservoir at the Kelvin temperature Th and a cold reservoir at the Kelvin temperature Tc.(a) If both temperatures are doubled, does the efficiency of the engine increase, decrease, or stay the same? Explain. (b) If both temperatures are increased by 50 K, does the efficiency of the engine increase, decrease, or stay the same? Explain.
ANSWER:
Step 1 of 3
Here, we have check whether the efficiency of the engine increases or decreases if the temperature is changed.
The equation for the efficiency of a heat engine,
Where, 
a)
