And the a gas liquid coexistent line.

这是气体——液体共存曲线。

Because this gas liquid coexistence line, this diagram, and this Clapeyron equation, is all done for a pure substance.

因为这个共存曲线，相图和克拉珀龙方程，都是对纯物质得到的。

Water exists in three states: liquid, gas, and solid.

水以三种状态存在：液体、气体和固体。

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。

The chemical conversion of natural gas to liquid fuels could provide an attractive alternative to CNG.

However, this form of energy requires expensive plants to turn the gas into liquid at source.
