Why vegetables are cooked with difficulty at a hill station?

Explanation

### Step-by-Step Solution:

1. **Understanding Boiling Point**: The boiling point of water is the temperature at which it changes from liquid to gas (steam). This temperature is typically 100 degrees Celsius at sea level.

2. **Effect of Atmospheric Pressure**: The boiling point of water is influenced by atmospheric pressure. When atmospheric pressure decreases, the boiling point of water also decreases.

3. **Altitude and Pressure**: At hill stations or high altitudes, the atmospheric pressure is lower than at sea level. This means that water will boil at a temperature lower than 100 degrees Celsius.
