Question
A Carnot air conditioner maintains the temperature in a house at $297 \mathrm{~K}$ on a day when the temperature outside is $311 \mathrm{~K}$. What is the coefficient of performance of the air conditioner?
Step 1
First, we need to find the efficiency of a Carnot heat engine operating between the two temperatures. The efficiency of a Carnot heat engine is given by: Efficiency = 1 - (T_cold / T_hot) Show more…
