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

可以通过氢气和氟气之间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，如果你把这种碳烧一下，你可以让成气态。

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.

我们在电离视频中看到，这就是为什么钠具有较低电离，在气态时只需很量就移除一个电子。

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，当我把分子吸进鼻子时，这个过程就开始了。这意味着你要闻到什么，气味必须是挥发性，或者处于气态，被吸进鼻孔。
