• So the triple point is liquid solid, gas, all in equilibrium.

    气态,固态,三相平衡,你可能会想。

  • 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。

  • Maybe you're not looking at a reaction, but you've got some new compound, and you're looking at it go from liquid to solid or to gas.

    也许你研究的不是一个反应,但你得到了一种新的化合物,你看着它从液体变成了固体或气体。

  • You take your room temperature liquid helium and you cool it with liquid nitrogen to 77 degrees Kelvin, the new, you're not quite there yet 77k unfortunately right? Then you take hydrogen you cool it would liquid nitrogen to 77, then you can use your hydrogen gas.

    首先要有常温的氦气,拿液氮把它冷却到77k,那个新来的7,你不坐在那儿,对吧?,然后用液氮把氢气降温到,然后就可以使用这个氢气了,想要用氢气来做焦耳-汤姆孙实验。
