I didn't even need to know that heat capacity of the product, right. Because it's effect the thermal mass of the product is negligible compared to the thermal mass of the calorimeter.

我甚至不需要知道生成物的,热容是多少，因为生成物的,热质量的作用相比于,量热计的热质量是可以忽略的。

"And I think the same way you get credit for a lot of the good things that happen, sometimes you have to take the heat for things that go wrong, even though you were not personally responsible in any of the wrong doing."

Is this possible? That's what the first law says it's possible; work is heat, and heat is work, and they're the same thing. You can break even 100% maybe. So let's go back and see what work is.

00%的效率,我们可以从大气中吸收热量，用来驱动我们的汽车,效率也应该能达到。
