Question

Does boiling point increase with pressure?

(a) True

(b) False

I got this question in an interview.

This intriguing question comes from Basic Drying Theory topic in division Drying of Food Processing Unit Operations

Answer 1

Correct answer is (a) True

The best I can explain: At higher altitudes, the atmospheric pressure is much lower therefore the boiling point is also lower. The boiling point depends on pressure up to the critical point. It is directly proportional to the pressure. At the critical point the gas and liquid properties are same.
