Why the food does not cook properly at hilly areas?

Explanation

### Step-by-Step Solution:

1. **Understanding Cooking and Boiling Point**: Cooking food typically involves heating it to a certain temperature, which is often at or above the boiling point of water (100 degrees Celsius at sea level).

2. **Effect of Altitude on Atmospheric Pressure**: As you ascend to higher altitudes, such as in hilly areas, the atmospheric pressure decreases. This is a fundamental principle of physics where pressure decreases with elevation.

3. **Boiling Point of Water at Different Altitudes**: The boiling point of water is affected by atmospheric pressure. At sea level, water boils at 100 degrees Celsius. However, as the altitude increases and the pressure decreases, the boiling point of water also decreases.
