Something I can measure and I can tabulate, and when I turn my dT knob here I know what's going to happen to the enthalpy.
----热容，我们可以用实验，测出热容并成表,当我知道这里的变量。

It works its magic, again, through purely instrumental means, so we can't really call those songs, and this puzzled me.
纯器乐的演奏方式,容我重申,能产生神奇的效果,所以我们其实不能把器乐称为歌曲,这让我很困惑
-
I didn't even need to know that heat capacity of the product, right. Because it's effect the thermal mass of the product is negligible compared to the thermal mass of the calorimeter.
我甚至不需要知道生成物的,热容是多少，因为生成物的,热质量的作用相比于,量热计的热质量是可以忽略的。

Let me talk a little bit about that context.
容我略谈一下当时的脉络。
-
When I flail my arms around I generate work and heat. This is not a constant volume process.
这不是一个恒容过程,但如果我是一个系统，当我做这些的时候。
-
Now, I know how to relate the heat flow to temperature change, through the heat capacity.
现在我知道怎样把能量的流动,和温度的变化联系起来，通过热容。
-
So if I worry about energy I have a pretty good chance of extracting out these heat capacities, right, and I don't have to worry about exactly which path and I can really mix things up.
而能量与热容有密切的关系,从能量就可以就算出这两个热容，我不需要考虑到底是哪一条路径,可以随意计算。

STUDENT: Just a quick question on some of the constraints, like isothermal, isobaric, isovolumetric expansion.
学生：我有个关于,等温，等压，等容等约束条件的小问题。

Cp, I forgot to put my little bar on top here because it's per mole Cp dT that's my dq here.
上面的Cv我忘记加上横线了,因为它也是摩尔热容。
