1·What is the energy unit in SI? The joule.
国际单位制中的能量单位是什么，焦耳。
2·In most fields, its use has been replaced by the 'joule'.
在大多数领域，这个单位已经被“焦耳”取代。
3·Szilard calculated that at room temperature one bit of information must take at least three thousand-billion-billionths of a joule of work to store.
西拉德计算出，室温下存储一个比特的信息至少需要消耗三十万兆分之一焦耳的功。
4·And we saw that, you saw that the Joule coefficient for an ideal gas was zero.
我们会发现，你们也会发现，理想气体的焦耳系数是零。
5·So the Joule free expansion involves opening this valve and asking what happens when this gas moves into the other bulb or distributes between the two.
焦耳自由膨胀就是,打开阀门后的过程,气体从一个腔跑到另一个腔,并在它们之间平均分配。
