AIPMT PRELIMS 2005 Physics Carnot Cycle MCQ Question
Type: MCQ-numerical-Medium-Class 11
An ideal gas heat engine operates in Carnot cycle between 227°C and 127°C. It absorbs 6 × 10⁴ cal of heat at higher temperature. Amount of heat converted to work is:
A
2.4 × 10⁴ cal
B
3.6 × 10⁴ cal
C
1.2 × 10⁴ cal
D
4.6 × 10⁴ cal
Correct Answer
Option C
Detailed Explanation
The efficiency of a Carnot engine is given by η =¹⁻ T₂/T₁. Converting temperatures to Kelvin and calculating gives the efficiency, which when multiplied by the absorbed heat gives the work done.
