Why does lowering the pressure cause a liquid to boil?
A. It becomes easier for molecules to escape.
B. It pushes molecules out of the liquid.
C. It causes the temperature to rise.
D. It changes the volume of the liquid.

Answers

Answer 1

Lowering the pressure in a container will cause the liquid in the container to boil faster because it becomes easier for the molecules to escape.

What causes boiling?

Boiling happens when the vapor pressure of a liquid equals the atmospheric pressure.

By lowering the atmospheric pressure, the vapor pressure of a liquid takes a lower time to equal the atmospheric pressure.

Thus, it becomes easier for the molecules of the liquid to escape from each other.
