Question

Cooking is difficult on mountains because

• A. boiling water is difficult at heights because of pressure variations
• B. water boils at only high temperature
• C. because of variations in humidity
• D. it is cool there

Answer 1

The correct option is A boiling water is difficult at heights because of pressure variations

At mountain, boiling temperature get reduced due to reduced pressure.

When the pressure above a liquid is reduced, the vapour pressure needed to induce boiling is also reduced, and the boiling point of the liquid decreases.
