SUMMARY
The efficiency of a Carnot engine operating between 230°C and 120°C is calculated using the formula eff = 1 - (Tcold/Thot). The temperatures must be converted to Kelvin for accurate results. The correct calculation yields an efficiency of approximately 52.83%, not the 47.83% initially obtained due to the use of Celsius instead of Kelvin. This highlights the importance of using absolute temperature scales in thermodynamic calculations.
