Answer:

As pressure increases, the energy required to boil a liquid increases because boiling point is the point where the vapour pressure equals or exceeds the atmospheric pressure.

Explanation:

The boiling point of something is the point where the vapour pressure equals or exceeds the atmospheric pressure, as stated previously. As temperature increases, more and more particles have enough energy to enter the gas phase. This increases the vapour pressure to equal or exceed atmosphere pressure, therefore, the liquid boils.
