Two liters of `N_(2)` at `0^(@)C` and `5` atm pressure is expanded isothermally against a constant external pressure of `1` atm untill the pressure of gas reaches `1` atm. Assuming gas to be ideal, claculate the work of expansion.

Explanation

To solve the problem of calculating the work of expansion for 2 liters of nitrogen gas (N₂) at 0°C and 5 atm pressure, which is expanded isothermally against a constant external pressure of 1 atm until the pressure of the gas reaches 1 atm, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Given Values:**
- Initial volume (V₁) = 2 liters
- Initial pressure (P₁) = 5 atm
- Final pressure (P₂) = 1 atm (after expansion)
