So we're going to compare the values for the triple point for water and carbon dioxide from two different sources.
00:07
The triple point is when all of the phases exist in tandem.
00:12
So there's gas, liquid, and solid present at the triple point.
00:16
So first i used the website.
00:19
So i got the triple point of water.
00:20
I had to use the google .com search for this because i couldn't find it on the website.
00:25
And then i found the pressure and bar and i converted it to tour.
00:29
And that's the conversion factor and you can also use this website to do the conversion or you can try converting it yourself using that factor so that is the value for water and then in figure 13 .18 a we see the phase diagram we can obtain the values from this diagram we can see that they're actually exactly the same so the data matches in both sources let's look at carbon dioxide the triple point temperature is is 216 .58 kelvin according to this website.
01:05
Subtract 273 .15 to get degrees celsius.
01:09
And then the pressure is this many bars or that many tours using this conversion factor...
