Because it's so important. And I should add and also under reversible work, where the external pressure is equal to the internal pressure.

所以传说在流传过程中,人们认为,“有三样礼物,那必定有三位国王“
But as you can see, in the run I'm talking about this, there really only are experiments in a couple of the dimensions of the educational purposes that we talked about in the very beginning.
但你们也看到了,我探讨这一点的过程中,所进行的实验只涉及到,我们在最开始谈到的,教育目标的几个方面。
But in terms of drugs that don't look like maybe this compound was used in the synthesis, many of them might have used thionyl chloride, because it generates such a nice reactive intermediate that you can go on and make a bunch of different compounds from that intermediate.
但是对于药物来说,它们可能跟合成过程中用到的这种化合物并不相像,很多药物的制造过程中都会用到亚硫酰氯,因为它能产生活性如此之高的反应中间体,以至于你可以继续利用反应中间体,来制造一堆不同类型的化合物。
Wrev w reversible. in this case here let's see this is it's a pressure is going down.
曲线下的面积,可逆过程的功,这个过程中。
And we saw that in fact in this case delta S of mixing, we calculated it, saw that it is positive.
实际上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。
He expressed his will that there be light, and there was light And that's very different from many Ancient Near Eastern cosmogonies in which there's always a sexual principal at work in creation.
他表达意愿希望有光,于是便有了光,这与古代近东的宇庙学解释有很大出入,在其中,创世过程中有性的因素。
And I wanted to do it a different way which is a little bit convoluted, but it introduces the idea of a thermodynamic cycle, and it's something that we're going to use a lot in the class.
现在我将用另一种,有些复杂的办法来推导这一关系,在这一过程中引入,我们今后会常接触到的,热力学循环的概念。
So the work that you're doing to expand, to go through this experiment, ends up cooling the gas.
因此在膨胀气体的过程中,气体降温。
Milton is telling us that he is himself in the process, still in the process, of maturing.
弥尔顿是告诉我们他自己也还正在,渐渐成熟的过程中。
And I take a great deal of gratification from my own writing.
而且,从我自己的写作过程中,我也体会到满足感。
And you can see what the heat involved in a process like that is as well.
你就能看到在类似这样的,过程中热量是如何变化的。
Otherwise you're going to waste some of that heat somewhere along the way, some of energy.
否则你就必须在这个过程中,浪费一些热量。
So w, the work is less for the irreversible process than the reversible process.
不可逆过程中系统对外界,做的功要比可逆过程时小。
Different sets of instructions. Anything else strike you as odd when you were reading this story?
这确实是不同的指令,还有其他的吗?,在你们阅读的过程中?
OK, you use the ideal gas law, etc., then you get a relationship that connects the pressure and the temperature, like here we got a relationship that connected the temperatures and the volumes together.
我们会得到,一个联系初末态,的压强和温度的,关系式,就像这个联系过程中。
So it seems like there's a favorable change in entropy going this way.
看起来在这个过程中熵增加是,有利于反应的。
u=0 And it's approximately equal to zero for all real gas processes.
在所有理想气体绝热过程中Δ,对真实气体近似为零。
p We want p equal to p external for the entire expansion, p2 and p external is decreased steadily from p1 to p2.
在膨胀过程中保持p等于外部,外部p很快从p1衰减到。
You couldn't just run something successfully in a cycle and get work out of it, using the heat from the hot reservoir, without also converting some of the heat that came in to heat that would flow into a cold reservoir.
如果一样东西在循环工作过程中,只有热从高温热源中流出,而没有热流入低温热源,那么此过程,不可能对外做功,不可能把所有热。
