转动能E是，它取决于有多少转动自由度,如果我有一个直线形的分子，只有两个转动自由度。

Or molecules. E rotational is, now it depends how many rotational degrees of freedom there are. If I've got a linear molecule, there are only two.

Higher entropy basically because you're forming molecules of gas where there weren't any before, and there's more disorder in the gas phase than in the liquid. That is, the gas phase molecules have more freedom to roam.

高的熵是因为,我们产生了以前不存在的气体分子,气体的无序程度比液体大，换句话说,气相的分子，有更多的到处游荡的自由度。
