Question

3. Boiling point of liquid changes with increase
in pressure. Why?

Answer 1

Answer:

As elevation increases, atmospheric pressure decreases because air is less dense at higher altitudes. Because the atmospheric pressure is lower, the vapour pressure of the liquid needs to be lower to reach boiling point. Therefore, less heat is required to make the vapour pressure equal to the atmospheric pressure

Answer 2

Answer:

Hey mate here is your answer...........✌️

Explanation:

Since a liquid vaporises when molecules move faster and farther apart. But when you increase pressure, you are applying an external force to hold molecules closer to each other. As a result, the rate of vaporisation changes and thus the boiling point changes.
