Due in 1 hour, 56 minutes 2 homework point(s) Phase Diagram The following diagram corresponds to a closed system, comprised of a pure substance. See section 16.11 "Phase Diagrams" in Zumdahl "Chemical Principles" 7th ed., pp 829-833 The letter labels closest to the points marked with a dot refer specifically to those points. The other letter labels refer to the region of the graph in which they lie Match the following: Dnormal gas region F critical point Iliquid and/or solid present at equilibrium -but no vapour Bnormal liquid region 1 of 3 https:/lewis chem.s phase%2ediagram%2eproblem 2016-04-02, 10:02 PM

Explanation / Answer

Part 1 - Metch the phases

D : Normal liquid region

F : Critical point

I : liquid and/or solid present in equilibrium - but no gas phase

B : Normal gas phase

H : normal gas and/or liquid in equilibrium - but no solid

G : solid region

D : triple point

A : supercritical fluid region

E : gas and/or solid in equilibrium - but no liquid

Part 2 - For the above phase diagram, the more dense phase in a solid-liquid equilibrium would be,

solid

Part 3 - The temperature at point F is called the,

critical temperature

Part 4 - The substance which can be liquified by increasing the temperature would be,

ice (H2O)

Part 5 : the substance which cannot be liquified at 1 atm is,

carbon dioxide (CO2)
