I. 서론
전하를 갖는 물질을 직류전기장에 놓으면 그 물질의 전하, 분자의 크기 및 모양 등에 따라 각각 하전 된 입자가 양극 또는 음극 쪽으로 특유의 이동을 한다. 이와 같은 현상을 전기영동(electrophoresis)이라 한다. 이동 정도의 차이에 의하여 물질의 분리 또는 순도를 검정하는 방법을 전기영동

and is rarely used nowadays except for some fruits. More sophisticated methods of drying have been developed recently, such as puff drying for breakfast cereals and popcorn. Vacuum andfreeze drying processes are used for products with delicate flavours and textures like coffee granules, eggs, prawns and vegetables. The process involves freezing, and evaporating the ice away, under reduced pressu

Theoretically, the freezing point of this should be the horizontal line, while the others should have some inclination.
However in this experiment, there are several temperatures which w
