Question

is pressure directly proportional to the boiling point of water? if yes, explain why ​

Answer 1

Answer:

The boiling point of water is not proportional to the atmospheric pressure. As the elevation increases, atmosphere decreases because air is less dense at high altitudes. Because the atmospheric pressure is lower, the vapour pressure of the liquid needs to be lower to reach boiling point.

Answer 2

$\huge{\underline{\underline{\boxed{\sf{\purple{Answer࿐}}}}}}$

The pressure of gas above a liquid affects the boiling point. In an open system this is called atmospheric pressure. The greater the pressure, the more energy required for liquids to boil, and the higher the boiling point.
