Objective
Purpose of this experiment
Understand the seperation principle of chromatography and identify the metal ions in mixture using paper chromatography
Principle of Chromatography
The stationary phase
Liquid or Solid used in absorbent in chromatography
The mobile phase
Liquid or gas moving through the stationary phase in chromatography
= Stefan-Boltzmann 상수
= 절대온도
단 원자 그리고 2원자 기체는 열복사를 투과한다. 그래서 열은 복사와 전도-대류 두가지에 의해 이러한 기체를 통과하여 흐르게 됨을 알 수 있다. 일반적으로, 복사는 고온에서 중요하게 되고 유체흐름 상황에 무관하다. 전도-대류는 흐름조건에 예민하고, 온도 준위에
Objection
Metals, ceramics, polymers that represent material engineering can find easily in our real life. Compare corrosion degree in case of uncovered in same corrosion environment and corrosion difference inquires happened reason.
Consider how take advantage of Material in state that is more better in our real life.
TheoryA
kind of the corrosion
- General Corrosion
