Give me the temperature and pressure and these two components, like water and alcohol, for instance, and I can tell you everything about the compositions. It's very powerful.
给我温度和压强,还有两种组分,比如说水和酒精,我可以告诉你组成的所有信息,这很强大。
And our question is, what we're going to be asking is, how many, if I give you the total pressure and the temperature here, what else do I need to know to find out all these molar fractions?
我们的问题是,如果我们被问到多少,如果给定总的压强和温度,我们还需要知道什么,才能知道混合的摩尔分数?
What I really want to do is just give an example of what happens when you throw the thing, the material into a calorimeter and see how much the temperature changes.
我想做的是给出当,你把这些东西,这些材料扔进,量热计时会发生什么,看看温度会变化多少。

They would bomb it, they would burn it, they would put it in this container inside water, and see how high the water temperature raises and that would give you a sense of the number of calories that it has.
研究人员会燃烧它,放入浸在水里的量热器,然后观察水温上升了多少,我们就对这种食物热量有所了解了
