Explain why cooking is difficult on hills and at high altitudes.

Explanation

### Step-by-Step Solution:

1. **Understanding Atmospheric Pressure**: At sea level, the atmospheric pressure is relatively high. However, as we go to higher altitudes, such as hills and mountains, the atmospheric pressure decreases.

2. **Effect of Low Atmospheric Pressure on Boiling Point**: The boiling point of water is the temperature at which its vapor pressure equals the surrounding atmospheric pressure. When the atmospheric pressure is lower, as it is at high altitudes, the boiling point of water decreases.

3. **Boiling Point of Water**: At sea level, water boils at 100°C (212°F). However, at higher altitudes, the boiling point can drop significantly. For example, at an altitude of about 2,000 meters (approximately 6,562 feet), water may boil at around 93°C (199°F).
