It can be formed in the gaseous state by an equilibrium reaction between hydrogen gas and fluorine gas.

它可以通过氢气和氟气之间的平衡反应以气态形成。

Or if you, kind of, if you burn this carbon, you can get it to a gaseous state.

或者如，如烧这些碳，可以把它成气态。

And we saw in the video on ionization energy, that's why this has a low ionization energy, it doesn't take much energy, in a gaseous state, to remove an electron from sodium.

们在有关电离能的视频中看到，这就是为什么它具有低电离能的原因，在气态下，从钠中去除电子不需要太多能量。

Now, the process starts as I sniff molecules up into my nose. This means that for you to be able to smell something, the odorant must be volatile, or in a gaseous state to get sucked up into your nostrils.

现在，当把分子吸进鼻子时，这个过程就开始了。这意味着要能闻到什么，气味必须是挥发性的，或者处于气态，被吸进鼻孔。
