What is the physical state of water at-
(a) `25^(@)` (b) `0^(@)C` (c) `100^(@)C`?

Explanation

To determine the physical state of water at different temperatures, we can analyze the conditions at each specified temperature:

### Step-by-Step Solution:

1. **At 25°C**:
- Water is in its liquid state. This is because 25°C is above the freezing point (0°C) and below the boiling point (100°C) of water.
- Therefore, at this temperature, water is commonly used for various daily activities such as drinking, cooking, and washing.
