Question

Spaghetti takes about 9 minutes to cook at sea level, but about 14 minutes in the mountains. Why do you think this is so?

Answer 1

At high altitudes, air pressure is lower. That means that the boiling point of water is lower as well (lower air pressure means that water molecules need less energy to turn into gas), and because the water is boiling at a lower temperature it takes longer for it to cook the pasta.

hope this helps!

Answer 2

Answer:

Cooking is done at lower temperature in high altitude

Explanation:

• Due to high altitude in mountain compared to sea level, pressure is lower than sea level.
• We know, boiling of a liquid depends on external pressure. With decrease in pressure, less temperature is required to boil a liquid. Because vapour pressure of liquid becomes equal to external pressure at a lower temperature in high altitude.
• So, during cooking of spaghetti, lower temperature is required to boil water. Hence cooking is done at lower temperature. Hence it needs more time to be properly cooked.
