Explanation

To solve the problem regarding the thermodynamic parameters for the process of converting liquid water (H₂O) to gaseous water (H₂O) at 1 bar and 373 K, we will analyze the changes in Gibbs free energy (ΔG) and entropy (ΔS) during the phase transition.

### Step-by-Step Solution:

1. **Identify the Process**: The process is the phase transition of liquid water to gaseous water at a constant temperature (373 K) and pressure (1 bar). This is a typical situation for boiling water.

2. **Equilibrium Condition**: At the boiling point of water (373 K) and at 1 bar, the liquid and gas phases are in equilibrium. This means that the system is at a state where the forward and reverse processes occur at the same rate.
