Water is cooled to 32K, and it appears to be on the solid phase on the phase changing diagram as the temperature is low.


Water is cooled to 32K, and it appears to be on the solid phase on the phase changing diagram as the temperature is low. We compress the ice to a temperature of 340-350K (around 30ATM on the pressure dial).

a. Where is the red dot now located in the phase changing diagram? Would it be on the line between liquid and gas phases?

b. What does that position on them phase change diagram say about pressure and temperature?

c. What happens to the pressure when heat is added?

d. How can you make the red ball move into the gas phase on the phase change diagram (using water in a simulation where you you can increase/decrease temperature and pressure)

Solutions

A phase diagram is a temperature-pressure plot that summarizes the conditions under which a substance exists as a solid, liquid, or gas. The curves that separate the phases are known as phase boundaries. Each phase boundary represents the equilibrium between the phases on either side of the curve.
