A scientist chaims to have developed 60% effcient engine while working between`27^@C and 327^@C`. Does he claim right ?

Explanation

To determine whether the scientist's claim of a 60% efficient engine operating between 27°C and 327°C is valid, we will calculate the maximum possible efficiency of a heat engine operating between these two temperatures using the Carnot efficiency formula.

### Step-by-Step Solution:

1. **Convert Temperatures to Kelvin:**
- The temperatures must be converted from Celsius to Kelvin because the Carnot efficiency formula requires absolute temperatures.
- \( T_1 = 327°C = 327 + 273 = 600 K \)
- \( T_2 = 27°C = 27 + 273 = 300 K \)
