Phase diagrams. A phase diagram lets you work out exactly what phases are present at any given temperature and pressure. In the cases we'll be looking at on this page, the phases will simply be the solid, liquid or vapour (gas) states of a pure substance. This is the phase diagram for a typical pure substance.

Phase diagram of o2.

Will $\ce{O2 (s)}$ float or sink on $\ce{O2 (l)}$? I quickly sketched the phase diagram of oxygen: Pressure of the molecules will affect how compact the molecules are in solid and liquid, so I guess we can explain whether it will float or sink using the slope? How does the slope tell us about the densities of $\ce{O2}$ solid and liquid ?

Consider the phase diagram for carbon dioxide shown in Figure 5 as another example. The solid-liquid curve exhibits a positive slope, indicating that the melting point for CO 2 increases with pressure as it does for most substances (water being a notable exception as described previously). Notice that the triple point is well above 1 atm, indicating that carbon dioxide cannot exist as a liquid ...

Recently, in the mixture of oxygen and nitrogen molecules, the appearance of a new solid phase, which does not occur for either pure component, has been reported under high pressure. We consider that the magnetic interaction of oxygen molecules would play a main role of the formation of the phase.
