So it would imply that CvdT du was equal to only the first term Cv dT.

这意味，这du进等于第一项。

youdao

So I could have written right here immediately CvdT equals Cv dT, and that was the end of my derivation.

于是我在这里就可以直接写,来它等于，完成了整个推导。

So if you get these two guys together you get CvdT=-pdV Cv dT is minus p dV.

把它们联系,起来。

dU=CvdT So du is still going to be equal to Cv dT, and we're still going to be able to use the first law, all these things don't matter where the path is.

于是，第一定律也依旧成立，这些关系都与路径无关。
