Modern extraction techniques can be based on dissolving

Solution 17 HP:

Step 1 of 2:-

Here we have to find how high the pressure and density of carbon dioxide, when the temperature and pressure at the critical point.

Here we can use the table A-2, where the data are as follows.

The pressure at the critical point is, .

The temperature at the critical point is, .

And .

So, the density will be,

.

So, the density at the critical point will be and the pressure will be .
