What is the efficiency of an ideal Carnot engine operating between temperatures T1 (source) and T2 (sink)?
A. 1 - (T2 / T1)
B. 1 - (T1 / T2)
C. (T1 - T2) / T1
D. Both 1 and 3 are correct✓ Correct Answer
💡 Solution & Explanation
The thermal efficiency of an ideal Carnot engine operating between absolute source temperature T1 and sink temperature T2 is expressed mathematically as 1 - (T2 / T1), which simplifies algebraically to (T1 - T2) / T1. Therefore, both representations are correct formulas derived from the second law of thermodynamics. Thermodynamics concepts are staple items in competitive science tests.
