事实上,这样定义出来的温标。
So we know that in each case the heat is going to be the opposite of the work, but the work isn't the same in these two different ways of getting from here to here, right. So let's just see it explicitly. Here's our qA.
所以我们知道在每种情形下功,与热量相差一个负号,但从这里到这里,在这两条路径,中的功是不同的,对吧?,那么让我们明确地看一下。
Let's look at the show of hands? All right so this is the majority here. Good thing physics doesn't work on the rule of the majority otherwise we'd be in big trouble.
