What will be the final volume of a mole of an idela gas at `20^(@)C` when it expands adiabatically from a volume of `5L` at `30^(@)C? C_(V)` of the gas `=5 cal//degree`.

Explanation

To solve the problem of finding the final volume of a mole of an ideal gas during adiabatic expansion, we can follow these steps:

### Step 1: Convert Temperatures to Kelvin
First, we need to convert the given temperatures from Celsius to Kelvin:
- \( T_1 = 30^\circ C = 30 + 273 = 303 \, K \)
- \( T_2 = 20^\circ C = 20 + 273 = 293 \, K \)

### Step 2: Identify Given Values
