Question

Rice boils in about 10 minutes at sea level. What happens to the boiling time at mountains?

• A. Time increases due to lower boiling point
• B. Time decreases
• C. No change
• D. Cannot be predicted

Hint:

Remember the relationship: Higher Altitude (implies) Lower Atmospheric Pressure (implies) Lower Boiling Point (implies) Longer Cooking Time. This is why pressure cookers are very useful at high altitudes. They create an artificially high-pressure environment inside the pot, which raises the boiling point of water above 100°C and allows food to cook much faster.

Answer 1

The Correct Option is A
