The partial pressure of the water, of gaseous water above that equilibrium of ice and water is not one bar, it's much less.
哪里错了吗?,问题在于,冰水混合物上方的,大气中水蒸气的分压,不是一个大气压。
I'm taking a class called AP Environmental Studies,

When it breaks this bond, that chlorine atom, a free chlorine atom comes down and reacts, this is ozone, with the ozone in the upper atmosphere.
当它打破这个化学键,氯原子,一个自由的氯原子下来,和在大气层的上方的臭氧反应,这就是臭氧,在大气上层有臭氧。
Is this possible? That's what the first law says it's possible; work is heat, and heat is work, and they're the same thing. You can break even 100% maybe. So let's go back and see what work is.
00%的效率,我们可以从大气中吸收热量,用来驱动我们的汽车,效率也应该能达到。
It's going to take place in there. It's going to be a constant pressure, it might be open to the air, or even if it isn't, there might be plenty of room, and it's a liquid anyway, so the pressure isn't going to change significantly.
也许它是液体,它在这个位置,这是恒压的,它也许是连通大气的,就算不是,它也有,足够的空间,而它是液体,压强不会显著地改变。
