1. Purpose
The objective of the experiment is to provide students with visual images of phase behavior of CO2 as well as observation of the solubility of materials in supercritical CO2.

2. Theory
2-1 Basic properties of Supercritical fluids
A supercritical fluid is any substance at a temperature and pressure above its critical point, where distinct liquid and gas phases do not exist. It can effuse through solids like a gas, and dissolve materials like a liquid. In addition, close to the critical point, small changes in pressure or temperature result in large changes in density, allowing many properties of a supercritical fluid to be "fine-tuned".
