Well, would it not increase with respect to the normal boiling point..........?

Explanation:

By definition, the #"boiling point"# of a liquid is the conditions of temperature and pressure when the #"vapour pressure"# of the liquid is equal to the ambient pressure and bubbles of vapour form directly in the liquid. The #"normal boiling point"# is specified when the ambient pressure is #1*atm#.

This underlies the principle of vacuum distillation, where an otherwise involatile liquid may be distilled at REDUCED pressure, and the material may be purified somewhat.

If the ambient pressure is somehow increased the temperature required for #"boiling"# also increases.
