So now I have my first of my two slopes, in terms of something that's related to my system the heat capacity of the system.

好，我们现在得到了，两个微分式中的一个,它等于与系统密切相关的一个量。

For most problems on exams, those quantities are constant, independent of temperature.

然后对于考试中的大部分问题，这些量都是与温度无关的常数。

So, why don't you take a look at this and tell me which are possible for a 2 s electron in a lithium atom where z 3 is going to be equal to three?

你们为什么不看一下这个然后告诉我对,于一个锂原子中的2s电子哪些是可能,的？它的有效电荷量,可能等于？

We want to have that definition clear because in fact we're going to, we might want tabulate heats of reaction, right, and of course want to know what the conditions are for the tabulated values apply. And we're going to want to calculate them from other quantities and again, we're going to need to know each case what are the relevant conditions?

我们想要明确这个定义,因为实际上我们会想把,反应热制成表格，当然我们会,想知道表中的数据在什么样的,条件下是有效的，我们会,想要从其他的量中算出它们,再一次，我们需要知道,每种情形下相关的条件是什么？
