Why cooking food in an open vessel takes more time at a hill station ?

Text Solution

AI Generated Solution

### Step-by-Step Solution: 1. **Understanding the Environment**: At hill stations, the altitude is significantly higher than at sea level. This means that the atmospheric pressure is lower. 2. **Effect of Atmospheric Pressure on Boiling Point**: The boiling point of water is affected by atmospheric pressure. At lower atmospheric pressure, water boils at a temperature lower than the standard boiling point of 100°C (212°F). 3. **Boiling Point at High Altitude**: Due to the lower atmospheric pressure at high altitudes, water may boil at temperatures around 90°C or even lower, depending on how high the altitude is. ...
