"And so, what we're trying to let them know is that we want to have a successful U.S.auto industry.

It makes sense, right, because you know we got less work out and delta u is the same right, so it must be that less heat got transferred.

这是显而易见的，因为输出的功更少,且Δu相等，所以需要的热量更少。

U And then if we can also determine delta u, then we know this, we know delta u is q plus w w, then we can determine work as well, right?

然后，如果我们也能定出△,然后我们知道这个,我们知道△U等于q加？
