Unformatted text preview: CHEMISTRY 1AA3 March 15-19, 2010 TUTORIAL PROBLEM SET 9 ______________________________________________________________________________ Page 2 of 2 6. For the phase diagram for CO 2 (right), what happens to a sample of CO 2 when the following occurs: (a) The temperature is increased from -100 °C to 0 °C at a constant pressure of 2 atm. (b) The pressure is reduced from 72 atm to 5 atm at a constant temperature of 30 °C (which is slightly less than the critical temperature of 31.1 °C). (c) The pressure is first increased from 3.5 atm to 76 atm at -10 °C and then the temperature is increased such that the CO 2 is subjected to conditions above the critical temperature and pressure. 7. Stinker. Compare the phase diagrams for water (right) and CO 2 (above). What is the significance of the change in slope between the solid-liquid boundary which is positive for CO 2 but negative for water? 8. Review test 2 solutions....
