We are asked to identify the three phase changes indicated by each arrow below in the phase diagram of water.
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
Identify the three phase changes indicated by each arrow below in the phase diagram of water.
