Calculate `q,w`, and `DeltaU` for the isothermal reversible expansion of one mole of an ideal gas from an initial pressure of `2.0` bar to a final pressure of `0.2` bar at a constant temperature of `273K`.

Explanation

To calculate \( q \), \( w \), and \( \Delta U \) for the isothermal reversible expansion of one mole of an ideal gas from an initial pressure of \( 2.0 \, \text{bar} \) to a final pressure of \( 0.2 \, \text{bar} \) at a constant temperature of \( 273 \, \text{K} \), we can follow these steps:

### Step 1: Understand the Process
Since the process is isothermal (constant temperature), we know that the change in internal energy (\( \Delta U \)) for an ideal gas is zero.

\[ \Delta U = 0 \]
