9.2.3 Caffeine, extraction with supercritical carbon dioxide, critical point
Materials can exist in three states: solid, liquid and gas.
You can change from one to another by altering temperature and / or pressure.
If you increase temperature and pressure enough, the distinction between liquid and gas will disappear at the critical point.
No phase boundary between liquid and gas exists, because at extremely high temperatures and pressures, the liquid and gaseous phases become indistinguishable.
The critical point of water is 374 o C, 218 atmospheres of pressure.
At above 31.1 o C and 72.9 atmospheres of pressure carbon dioxide behaves like liquid and like a gas.
It spreads out like a gas to fill the available space and can dissolve substances as if it was a liquid.
The low temperature is convenient, because it can be used with substances that would be damaged by the high temperature.
