I'm going to write it like this three moles of hydrogen which is a gas one bar 100 degrees Celsius.

我会写成这样：,三摩尔氢分子，气体,1巴，100摄氏度。

Here just two, so we changed the number of moles of gas by three. All right, how much did it matter, right?

所以我们将气体的摩尔数,改变了3摩尔，好，它会起多大作用？

Now going from three to four right, so we have another isothermal process for an ideal gas, so I won't try to make you sing again so soon.

从第三点到第四点，这也是一个理想气体的,恒温过程，这次不用你们集体回答了。
