One mol an ideal gas is expanded from`(10 atm, 10lit)`. `(2 atm , 50 lit)` isothermally . First against 5 atm
then against 2 atm . Calculate work done in each step and compare it with single step work done.

Explanation

To solve the problem of calculating the work done during the isothermal expansion of one mole of an ideal gas, we will follow these steps:

### Step 1: Understand the Initial and Final States
- Initial state (State 1):
- Pressure (P1) = 10 atm
- Volume (V1) = 10 L
- Final state (State 2):
- Pressure (P2) = 2 atm
