So for the reversible process, the work done is the integral under the pressure volume state function, the function of state.
对可逆过程,做的功,是压强体积态函数曲线下,的积分面积。
It's a state function, so we're at constant temperature and pressure, and now we want to consider some chemical change or a phase transition or you name it.
这就是态函数,我们处于恒定的温度和压强之下,然后考虑某些化学变化或者相变,或者你想考虑的东西。
Similarly for G as a function of temperature and pressure, I can go through the same procedure.
同样的G作为,温度和压强的函数,我可以采用相同的步骤。
What is dH/dT as a function, keeping pressure constant, what is dH/dp, keeping temperature constant?
恒定时偏H偏T是什么,温度恒定时的偏H偏p又是什么呢?,好的,让我们解决第一个问题?
If you want to write a function that describes this line here, it's pressure as a function of volume related to each other with this constant.
如果要写出描述这条等温线的方程,它的压强和体积,就通过常数C相联系起来。
And that shows us that H is written naturally as a function of entropy and pressure.
这证明自由焓H很自然的可以写成,熵和压强的函数。
