Question

Why does it take longer to cook food in the mountains than in the plains? Evaluate the following statements.

Statement I: Water boils hotter at lower pressure.

Statement II: Lower atmospheric pressure lowers the boiling temperature of water in an open pan.

TestHub · Accepted Answer

Atmospheric pressure is lower at height, so water boils below 100°C. Open water cannot get hotter than its boiling point, so food cooks at a lower temperature and needs more time. Statement I is false and Statement II true. Correct option: (C).
