OK, so this, what I've sketched here would be a constant pressure calorimeter. There's a reaction.
好,我画的就是一个恒压量热计,其中进行一个反应。
I mean, the weather is always nice. I mean, it never gets too cold, never gets too hot.
天气一直很好。不会太冷,也不会太热。
All right, let me just go through one numerical example of a calorimetry calculation, OK.
好,让我们来做一个量热,法计算的例子,我不会把所有的。
And if I do that then I can find out the change in enthalpy of this reaction. It's just going to be the heat of formation of these three moles of water, minus the heat of formation of the iron oxide. OK.
我就能得到这个,反应的焓的变化,它就是三摩尔水,的生成热,减去氧化铁的,生成热,好。
so that's what we think we know in constant pressure calorimetry.
好,我想这就是我们,在恒压量热法中所知道的。
See you Friday. We'll finish on calorimetry and thermochemistry and then we'll start in on one of the really most difficult topics that we'll deal with all semester, which is a second law and our special function that
好,我们周五见,我们会讲完量热法,和热化学的内容,然后我们会开始,讲这个学期最难的话题之一,第二定律以及我们
OK, so let's do some thermochemistry.
好,让我们来做一些热化学。
