Boiling point
Saturation temperature and pressure
Critical temperature and pressure
Use a phase diagram to estimate change in boiling point with pressure
3.4.3
What about in the opposite direction, as pressure increases what happens ?
Are there any limits, either increasing or decreasing pressure?
Do you think this will continue indefinitely?
3.4.4
In this unit we will continue to investigate the phenomena of liquid to vapour phase change. The term “boiling point” is very common and we will explore further what this implies.
We will review the concept of saturation temperature, commonly referred to as the boiling point and then explore how saturation temperature varies with pressure.
