The Saturation Point of a substance is the temperature at which a liquid boils at a given pressure.

Saturation Temperature – can be defined as the temperature of a liquid to change its state from a liquid to a gas throughout the bulk of the liquid at a given pressure.

Pressure and Boiling.

Where atmospherical pressure is less, liquid will boil at a lower temperature. In contrast, at higher atmospheric pressures, a liquid’s boiling point increases. This is because the particles in a liquid need more kinetic energy to escape. 

So we can now understand that a liquid can only absorb so much heat energy until it reaches its saturation point.  This liquid will have a definite saturation temperature however this varies on the atmospheric pressure of it surroundings.  We can also assume that if we lower or increase pressure deliberately we can increase the amount of heat energy a substance can absorb before boiling.  Likewise if we lower the pressure we can also lower its boiling point.
