phase diagrams?
Use the phase diagrams in Chapter 11 of your text to determine which of the following are true statements.
a) Above 31oC and 73 atm CO2 is in its supercritical state
b) For water the melting temperature increases as the pressure increases
c) For CO2 the melting temperature increases as the pressure increases
d) CO2 at 50oC and 2.5 atm is in the vapor state
NOTE THERE IS MORE THAN ONE ANSWER
I think you need to spend a few minutes trying to understand the phase diagrams in the chapter. Each line on the diagram represents a transition from one state to another. The axes of the diagrams are temperature and pressure. I'm sure you'll need to learn to interpret these diagrams for an exam, so you might as well start now...
