Increasing pressure usually increases the boiling point of a liquid. A way to think about it is that the molecules of the liquid need more energy to break into the gas phase when the more molecules are hitting the surface of the liquid with more energy. For melting point, increasing the pressure makes some difference.
The boiling point of liquids always increases when pressure is applied on a liquid. This is because the molecules of a liquid will need more energy to turn into a gaseous state when pressure is applied on that substance.
