为了能够维持生命，这个新的星球不仅要有液态水，而且它的土表还必须是固态的，就像地球这样。

To be able to support life, the new planet would need not only to have water, but it would also need to be solid.

第一步,我将要将固态的钠气化。

The first thing I am going to do is I am going to convert the sodium into vapor.

你知道这个量大于零，因为液态的熵，大于固态的熵。

And you know that's greater than zero because the entropy in the liquid state is much bigger than it is in the solid state.

You could run the reaction, take solid iron gaseous oxygen, form iron oxide, measure the heat of formation of it, tabulate it.

你可以进行一个反应,用固态铁和氧气生成氧化铁，测量它的生成热，列成表格。

Now in this particular reaction, I've got hydrogen gas, iron solid. Those already are elements in their most stable forms at room temperature and pressure.

特定的反应中，我有氢气,固态铁，这些都已经是,处于室温和常压下,最稳定的元素单质。
