How is heat content at constant pressure and that at constant volume be related to vapourization of water at `25^(@)C` ?

Explanation

To relate the heat content at constant pressure (enthalpy, ΔH) and at constant volume (internal energy, ΔE) for the vaporization of water at 25°C, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Reaction:**
The vaporization of water can be represented as:
\[
\text{H}_2\text{O (l)} \rightarrow \text{H}_2\text{O (g)}
