2) Helium is a noble gas. 氦气是惰性气体。3) monoatomic gas 单原子气体4) monatomic ideal gas 单原子理想气体 1. After four quantities of the monatomic ideal gas and quantum gas were calculated,the utility of N-E-V distribution will be verified. 本文推导了统计热力学中粒子数N、能量E...
网络氦气是惰性气体;氦气是钝气 网络释义
In order to produce natural gas with an acceptable level of heat energy, these impurities must be removed. This process is called upgrading. There are several methods used to upgrade natural gas. When the gas contains more than about 0.4% helium by volume, a cryogenic distillation method is ...

Why is oxygen the most abundant element compared to the others? Consider the substance: helium gas. Classify this substance as a pure substance or a mixture. Explain or prove your answer. Give three reasons why carbon is preferred over hydrogen in the relative atomic mass of an atom. ...
While most materials become solid at temperatures below 0°C (32°F), helium becomes liquid. Helium does not ignite at higher temperatures. After hydrogen, helium is the most abundant element and has the symbol (He). The gas belongs to group O in the periodic table. ...
the seventh element of the periodic table between carbon and oxygen is nitrogen. it’s an important part of amino acids. around eighty per cent of the earth’s atmosphere comprises nitrogen gas. it has no colour, mostly diatomic non-metal gas which is odourless and colourless in nature. ...
