Question 2 of 126

The efficiency of a Carnot engine operating between 27∘C27^\circ\text{C} and 327∘C327^\circ\text{C} is:

Show answer and solution

Answer: (C) 50%50\%

T1=327+273=600 KT_1 = 327+273 = 600\,\text{K}, T2=27+273=300 KT_2 = 27+273 = 300\,\text{K}. η=1−300/600=0.5=50%\eta = 1 - 300/600 = 0.5 = 50\%.
