So the first step to doing that is I want to just generalize our results so far for a Carnot cycle.
第一步,首先来推广一下,卡诺循环的结果。
Take small steps.

What was the key step that I said I needed to do on Friday but failed very publicly to do so?
至关重要的一步,我将在本周五跟大家细细道来,如果我很嚣张地失败了怎么办?
now let's go back to each of our individual steps and look, based on what we know about how to evaluate the thermodynamic changes that take place here, let's look at each one of the steps and see what happens.
让我们回到循环中的每一步,然后看看,基于我们已有的知识,来估计一下,发生的热力学变化,让我们看,循环中的每一步发生了什么。
Once you're doing this on your own, -- especially, for example, on exam 2, which is a ways down the road, you won't be able to look at those steps, so you need to make sure that you can go through them without looking at them, but for now we can look at them as we are actually learning how to draw the Lewis structures, and rather just go through them step-by-step, it's more interesting to do it with an example.
每当你要画一个路易斯结构的时候,特别是,比如,在第二次考试中,在不远的将来,你将看不到这张表,因此你需要确保自己在不看这张表,的情况下也能按照上面的流程来画,但是目前我们是可以看着这张表,来学习如何画路易斯结构的,而相比于一步一步地讲,通过例子来演示一下会更有意思。
And there's some other ideas like that where we step back and really try to understand these investors and hopefully partners with entrepreneurs.
还有些其他观点,比如我们应该如何,退一步来真正试着去理解这些投资者,然后充满希望地与企业家合作。
It's reversible, that means that p external, equals p. I'm doing it very slowly so that I'm always in equilibrium between the external pressure and the internal pressure so I can go back and forth.
