TRANSPORTABLE GAS TO LIQUID PLANT 可运输的天然气转变液体燃料工厂
Latent heat is absorbed or released whenever matter changes phase, as when matter changes from liquid to gas, for example, or from gas to liquid.
潜热在物质形态变化时被吸收或释放,例如当物质从液体变为气体或从气体变为液体时这一过程就会发生。
So we can replace this with the change in Gibbs free energy from going from gas to liquid.
所以这一项我们可以替代它,用从气相到液相变化的吉布斯自由能。
They base this on the previously unconsidered drop in pressure that occurs when water passes from gas to liquid state in condensation.
这是根据先前当水因冷凝由气态变为液态时,气压骤降而得出的。
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。
