This question is asking for the effect of pressure, pressure on the melting point of co2.
00:12
So for us to answer this question, first of all we have to draw a sketch of the co2 phase diagram.
00:20
Say we've got p against t.
00:23
We know that the co2 phase diagram looks like something like this, where this is the triple point.
00:31
So this is the gas phase, this is the liquid phase and this is the solid phase.
00:40
So we are looking at melting, melting point.
00:46
So the phase or the equilibrium cave that we are interested in is this one.
00:55
This is the equilibrium cave that we are looking at because remember melting is the change of phase from solid to liquid.
01:06
So we are looking at this cave because this is the only cave that relates the solid to the liquid phase.
01:14
So when we are increasing pressure, we can look at this.
01:18
If we are increasing pressure, we can notice that we are also increasing the melting temperature or the melting point...
