Calculate the efficiency of a carnot engine working between the two temperatures: `30^(@)Cand 100^(@)C`

Explanation

To calculate the efficiency of a Carnot engine working between two temperatures, we follow these steps:

### Step 1: Identify the temperatures
We are given two temperatures:
- T1 (hot reservoir) = 100°C
- T2 (cold reservoir) = 30°C

### Step 2: Convert the temperatures to Kelvin
