분광 광도법(spectrometry)
빛을 흡수하는 성질을 가진 분자, 원자 또는 이온은 특정한 파장의 빛에너지에 대해 기여하고 이것이 물질의 고유현상을 나타내는데 이러한 방법을 분광 광도법이라 한다. 분광 광도법은 빛의 세기를 측정하는 방법 중 하나로 빛의 스펙트럼을 이용하여 각 파장에 대한 빛에너
connected by covalent chemical bonds. Although the term polymer is sometimes taken to refer to plastics, it actually encompasses a large class of natural and synthetic materials with a wide variety of properties.
Because of the extraordinary range of properties of polymeric materials, they play an essential and ubiquitous role in everyday life. This role ranges from familiar synthetic plastics a
Oxidation -Reduction reaction
When one molecule is near another one, there is chemical reaction from which electrons from one molecule to another molecule moving in a chemical reaction can occur simultaneously. Thus, this is called Oxidation -Reduction reaction.
Equivalence point & End point ?
End point is the point that we can expect titration is over by observing system’s states
1. ABSTRACT
이번 실험에서는 학부 실험실내에서 건∙습구 온도계를 이용해 상대습도를 구하고, 기압, CO2의 농도를 측정하였다. 이는 비교적 간단했던 실험으로 건구 ∙ 습구온도계와 습공기선도를 읽는 방법, 수은 기압계, CO2농도 측정기의 사용법을 충분히 숙지하는 것을 우선으로 했다.
2. Exp
The transfer of thermal energy between neighboring molecules in a substance due to a temperature gradient.
2) It always takes place from a region of higher temperature to a region of lower temperature, and acts to equalize temperature differences.
3) Conduction takes place in all forms of matter. (solids, liquids, gases and plasmas)
Thermal conductivity k is physical property of the su
