1. Objectives
1,1 용액의 부피를 정확하게 예측하는데 필요한 부분몰부피를 측정한다.
1.2 분자들의 모양, 크기, 극성에 따라 부분몰부피가 어떻게 달라지는지 서로 비교한다.

2. Theory
2.1 The reason CO_2 SCF used in this the experiment
Since CO_2 has a high density, it can be used as a solvent and is non-flammable, non-polar, and non-toxic, so safety and harmlessness to the human body can be secured at the same time. In addition, CO_2, which is a gas at room temperature, can solve the environmental problem of residual solvent treatment, and the fact that it is relatively inexpensive is considered an advantage that can not be overlooked.

2.2 The CO_2 phases change below its critical point to above its critical point
Under pressure and temperature conditions below the critical point, water or carbon dioxide exists in gas, liquid and solid phases. The curve drawn on the phase means the temperature and pressure conditions in which the two phases coexist in equilibrium.
