You calculate how much heat is released in the reaction. And then what's going to matter is what's the heat capacity of the whole, of the calorimeter?

就是计算在反应中,放出了多少热量,接下来关键的是,整个量热计的热容是多少？

And it's for that whole unit that you've got some heat capacity. How much heat does it take the warm the entire thing up or the insides of the thing up by a degree? It's that number right.

由这个单位你能知道,一些热容的信息，要让这整个装置,或里面放置的东西,升温一度需要多少热量？

The heater is on, it's producing heat until a negative signal is registered, 'oh we've gone too high', and then it turns off.

加热器会开着,一直产生热量直到它得到一个关闭的信号,噢我们弄得太热了,然后就关闭了
