And the path that I'm describing then, let's assume that we're raising the temperature up is this path right here.
经过一个,等压过程,路径就是这样。
Path number 2 on my diagram it's a reversible, this path number 2, it's a reversible constant pressure path.
路径,首先是一个,等压过程。
We're not going to have the constant pressure heat capacity, we're going to have the constant volume heat capacity, right.
这里出现的,不是等压热容,而是等体热容。
So then, going from the initial to final states with a red path, ou start with an isobaric processand then you end with an isothermal process.
因此沿着,这条红色路径,你从一个等压过程开始,以一个等温过程结束。
So, this path right here from this top red path is an isobaric process.
所以上面这条红色的路径,就是个等压过程。
If you have an isobaric you're going to have to calculate where the energy changes, and that's a calculation that's likely on the homework and very like on an exam as well, too.
在等压过程中,我们需要计算能量的变化,我们在作业,和考试中,就会遇到这类问题。
So the first path then, the first path, 1 constant volume constant V, so I'm going to, again, let's just worry about energy.
首先,是路径,等压过程。
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。
Could be done, but easier is to just do the whole thing at constant volume, right, and just run the reaction that way and redo the calculation to be a constant volume rather than constant pressure calorimeter, right.
可以进行测量,但是如果在体积恒定的条件下,做这些会容易得多,还是这样进行反应,但是在等体而不是恒压条件下重新计算。
So that's going to have to be a constant pressure path.
它应当包含,一个等压过程。
Whereas, like isobaric means constant pressure.
等压“指压强不变。
Cp And delta T is given by the heat, which has to do with how much of the candle burnt, divided by the constant pressure heat capacity.
T等于热量q除以恒定的等压热容,其中热量与,蜡烛燃烧的多少相关。
