It's only entropy that's going to contribute. Ok, let's look at just one more entropy driven problem. And that is, it's a little bit different from these let's look at the entropy mixing in a liquid.
那之后只是熵在起作用,好,让我们再来看一个熵驱动的问题,它和这些有一点不同,让我们看看液体中的熵的混合。
If we calculate the change in entropy during gas mixing, we will find that this quantity is positive.
如果我们计算气体混合过程中熵的变化,我们会发现这个量是正的。
So we can just explicitly calculate the entropy of mixing.
这样我们能更明确地,计算混合后的熵。
Without entropy of mixing, then everything would go directly to the products.
没有混合熵的话,所有的东西都会变成产物。
So entropy of mixing is really super important.
所以混合中的熵是非常重要的。
Without entropy of mixing, we would be sitting on this curve here.
没有混合熵,我们得到的就是这条曲线。
All driven by entropy of mixing.
所有这些都是由混合熵引起的。
Because you've got entropy of mixing happening in all of this.
因为我们得到的是所有这些混合的熵。
If that's not zero, unlike the ideal case, now unlike before, where we just had entropy driving the mixture, now there's an energy of mixing.
如果那不是零,和理想的情况不同,和以前不同,以前我们只有熵来驱动混合,现在有混合能。
Specifically, how entropy of mixing really becomes key to equilibrium.
特别地,为什么熵的混合,对于平衡态如此重要。
So that's our entropy of mixing.
那就是我们混合物的熵。
So now I've got the entropy of mixing even in a condensed phase the liquid.
那么现在我们已经得到混合物的熵,即使对相对浓缩的液相。
What's the magic word? Entropy of mixing, right.
魔幻词汇是什么?混合熵。
If I have nothing, if I have no a here, up here and just the inert gas, then there's no entropy of mixing.
如果没有A物质,而只有惰性气体的话,那么就不会有混合熵。
If entropy of mixing wasn't there, I would start from up here.
如果没有混合熵,那么就是从这里开始。
And it's all driven by entropy of mixing.
这些的基本原因都是熵的混合。
Which is to say there's an entropy change in mixing.
那就是说,混合后有熵变。
I add a little bit of inert gas, there's a little bit more entropy of mixing.
加入一点惰性气体,就会有一点混合熵。
Right. There's more entropy of mixing if you've got a mixture in the liquid than if you have a pure gas up there.
对,最终的熵会更大,如果你把液体混合的话,会比纯物质的熵大。
Let's now look at the entropy of mixing.
让我们来看看混合熵。
The entropy of mixing of reactants and products wasn't there.
没有反应物和生成物的熵。
D Because if I have equal amounts of a, B, c, and d, that's a lot of entropy of mixing there.
因为如果我们有等量的A,B,C和,那么混合熵会很大。
And the entropy of mixing was really super important.
混合熵非常重要。
B So when you mix a and B, you're going to have the same entropy of mixing.
当混合a和,有同样的混合熵。
Just from the entropy of mixing.
因为混合熵。
Entropy of mixing comes in here.
熵从这来。
The mixing degree of atomic initial state has no influence on the entropy squeezing of the atom in motion.
原子初态的混合度对运动原子的信息熵压缩几乎没有影响。
The entropy generation and the exergy loss vary similarily with the change of mixing ratio, they first increased then decreased and both reached a maximum at a fraction of COG around 48%.
随着混合比例的增加,混合熵增加和损的变化规律相同,即先增大再减小,且在焦炉煤气体积分数约为48%处达到极大熵增加和损。
The alloys with high pack density possess high mixing entropy and high glass forming ability.
具有较高堆积密度成分的合金具有较高混合熵和较高的非晶形成能力。
