But let's start from the beginning: do you know Avogadro's principle? How many molecules of gas in one mole of the monoatomic gas? How many molecules of gas in one mole of the diatomic gas? How many atoms of gas in one mole of the monoatomic gas? How many atoms of gas in one ...
14 A gas is heated in a sealed container.The volume of the container does not change.What happens to the molecules of the gas? B A The average distance between molecules increases. B The average kinetic energy of the molecules increases. C The mass of each molecule increases. D The volume...
When we say "20% by volume" we mean "as if the gas was kept at the same pressure as other mixture components".So, 20% by volume of oxygen in the air means if you have 1L of the air at 1atm you can think about it as if it was a mixture prepared by using 0.2L of oxygen at...

根据《石油化工可燃气体和有毒气体检测报警设计标准》规定，测量范围应符合下列规定：（）的测量范围为爆炸下限的0～100%LEL；（）的测量范围宜为0～300%OEL，当现有探测器的测量范围不能满足上述要求时，（）的测量范围可为直接致害浓度0~30%。
Once purchased, solar generators have no running costs aside from occasional maintenance. This makes them a cost-effective long-term solution for eco-conscious homeowners. Final Thoughts Understanding how much gas a generator uses to power your house involves considering various factors, including the ...
A. The volume of a gas at constant temperature varies inversely with the pressure exerted on it. B. When a current flows in a conductor the amount of heat generated is proportional to current, resistance, and time in the current flowing. C. It is impossible for any device that operates ...
However, the organization can also choose to expand without necessarily consolidating an operation, as would be the case when a company builds out its own retail network. Theoil and gas industryhas been particularly active in vertical integration, as firms in the sector tend to have con...
