FREE Expert Solution

Recall that a phase diagram shows the transition of matter between solid, liquid, and gas phases as temperature and pressure changes.


In a phase diagram, the different phases can be identified by their location:

 Solid: can be found at high pressure and low temperature

 Liquid: can be found between the solid and gas regions

• Gas: can be found at low pressure and high temperature
