Because eventually they will tell us maybe things about how heat is changing further on.
我们需要知道焓在系统中怎样变化,因为最终它们或许会告诉我们。
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
Or I could have a non-adiabatic, I could take the same temperature change, by taking a flame, or a heat source and heating up my substance. So, clearly q is going to depend on the path.
也能改变温度,绝热指的是没有热传递,在非绝热条件下,也同样可以升温,比如用火或者热源加热,这样,q也应当与路径有关。
