我们能进行计算这些值，如果我们这样做，我们能算出是，2。18，乘以10，的负18焦耳。

And we can go through and calculate the value of this quantity in parenthesis. And, when we do so, we get the value 2.18 times 10 to the minus 18 joules.

事实上焦耳的确做了这个实验，他做到了，他能达到的最好实验要求，发现在可测量范围内没有观察到温度上升。

Joule actually did this experiment, and he observed that for the gas expansions that he could do, that the temperature did not increase measurably.

所以如果你们带了计算器，希望你们也能确认一下，我们算出的答案，能量等于，7,82乘以10的- 19次方焦耳。

So hopefully if some of you have your calculators with you, you can confirm the answer that I got, which is that the energy is 7.82 times 10 to the -19 joules.

Also to point out, a lot of times you'll see electron volts instead of joules, this is the conversion factor here just so you all have it in your notes.

同样也要指出，很多情况下你会看到,电子伏特而不是焦耳，这里是换算因子,你们在讲义上都能找到。

And if you do so, you will end up with 1.312 mega joules per mole for this quantity K.

这样做之后，对于K常量你就能得到2,1。312百万焦耳每摩尔。
