What is the physical state of water at: a. `250^(@)C` b. `100^(@)C`?

Explanation

To determine the physical state of water at different temperatures, we need to consider the boiling point of water and the temperature in question.

### Step-by-Step Solution:

1. **Understanding the Boiling Point of Water**:
- The boiling point of water is `100°C`. At this temperature, water transitions from a liquid state to a gaseous state (steam).

2. **Analyzing Water at `250°C`**:
...
