Channel: Professor Heath's Chemistry Channel
Date: 2013-12-04

For the phase diagram of carbon dioxide answer the following questions:
a) What phases are present at point C?
b) What phases are present at point B?
c) Starting at point B, if you decrease the pressure to 0 atm and keep the temperature the same what phases will you go through? What is the name of the phase change?
d) Starting at point A, if you increase the temperature and keep the pressure the same what phases will you go through? What is the name of the phase change?
e) Starting at point C, if you decrease the temperature and keep the pressure the same what phases will you go through? What is the name of the phase change?
f) What phases are present at point D? What is the name of this point?
g) What is the name of point E? What happens above this point?
h) What point on the graph represents the normal sublimation point of carbon dioxide? At what temperature does sublimation occur?
i) What is the pressure at the triple point?
e) Is the liquid or solid phase more dense for carbon dioxide?
