Question

Use the following data to draw a rough phase diagram formethane:
triple point -183.0°C critical point -83.0°C
normal melting point -182.5°C critical pressure 45.6 atm
normal boiling point -161.5°C

a. What is the stable phase of methane at -160°C and 2.0 atmpressure?

b. At a constant temperature of -182°C, the pressure on a sample ofmethane is gradually increased from 1.0 mm Hg to 1.0 atm. Whatphases would be observed, and in what order would they occur?




Matchingpairs
a. stable phase - Select choice - (liquid, gas,gas then liquid then solid, solid then gas, liquid then gas, solid,solid then liquid, gas then liquid)


b. phases observed - Select choice - (liquid, gas,gas then liquid then solid, solid then gas, liquid then gassolid,solid then liquid, gas then liquid)
