Question

Which of the following condition is/are correct regarding the boiling point of a liquid with an increase in pressure?

(a) Decreases up to triple point

(b) Increases up to triple point

(c) Increases up to the critical point

(d) Decreases up to the critical point

The question was posed to me at a job interview.

I'm obligated to ask this question of Eight Forms in chapter Eight Forms of Corrosion of Corrosion Engineering

Answer 1

Correct choice is (a) Decreases up to triple point

The best I can explain: As the pressure of a liquid decreases, its boiling point decreases up to its triple point. As the pressure increases its increases up to a critical point.

Example: At higher altitudes boiling point of liquids reaches low as atmospheric pressure decreased.
