But this is a compound, right, it has some non-zero heat of formation from the elements. So is water, right?

但这是种化合物，对吧？,它具有非零的生成热,水也是一样，对吧？

for instance, for the thermos with the coffee in if you place the boundary in the inside wall of the glass or the outside wall of the glass and the inside of the thermos, that makes a difference; different heat capacity, etcetera.

比如说，对于装咖啡的热水瓶来说,你把边界设置在瓶胆的内壁上,或者设置在瓶胆外壁上,或设在热水瓶里面，情况都是不一样的;,有不同的热容等等。

You couldn't just run something successfully in a cycle and get work out of it, using the heat from the hot reservoir, without also converting some of the heat that came in to heat that would flow into a cold reservoir.

如果一样东西在循环工作过程中,只有热从高温热源中流出，而没有热流入低温热源，那么此过程,不可能对外做功,不可能把所有热。

And that generally is just given by the heat capacity the calorimeter times delta T, right.. Because the heat capacity of the calorimeter just like this thing is not strongly temperature dependent, OK.

一般它就由量热计的热容,乘以ΔT给出，因为，量热计的热容,就像这张桌子一样,并不强烈依赖于温度。
