Phase diagrams are useful because they let us see, they let us predict what phase substance will be in at a given temperature and a given pressure.
00:12
And they also let us see how a substance changes phases at different temperatures and pressures.
00:26
So we typically start out.
00:34
So usually this is our vapor phase right here.
00:41
And as temperature increases, then we can stay in the vapor phase.
00:45
At higher temperatures.
00:48
And our solid state phase is over here.
00:55
And our liquid is right here.
01:00
So from what we can see, i'm sorry, i just realized i've got these backwards.
01:33
So what this graph tells us is that when the temperature is very low, we're going to be in the solid state...
