It's important to understand that increasing external pressure will actually increase the boiling point of a liquid. This is because the liquid needs to exert a higher vapor pressure to overcome the increased pressure from the surroundings and boil.

So, if you were to increase the pressure above standard pressure, the boiling point of isopropyl alcohol would be higher than 82.5°C.
