Why does lowered air pressure allow water to boil at room temperature?

A. The kinetic energy of the liquid molecules increases, causing gas

to form.

B. The mass of the liquid is reduced, making it easier to form a gas.

C. Less force pushes down on the liquid, making it easier for gas to

escape.

D. The lowered air pressure increases the temperature of the liquid.

Less force pushes down on the liquid, making it easier for gas to escape.

The correct option would be A where it reports that "The kinetic energy of the liquid molecules increased, causing gases."

Explanation:

The kinetic energy of water increases by placing a temperature increase on the liquid, in this way the particles collide with each other releasing energy, this energy is what corrupts the liquid state and becomes a gaseous state.

The water undergoes this process could be said that in the gaseous state its volume increases and disperses in the medium in an unlimited way like any gas.
