There's still not nearly enough thermal energy to have a molecules up here. So what, was the derivative of the energy with respect to the temperature?
仍然没有足够的热能使分子上升到这儿，那么相对于温度得到的，能量又如何呢？
So one way to get a small change in temperature is to take a derivative with respect to temperature.
所以得到温度微小变化的一种方法，就是对温度求导。
And what that says is that the heat capacity and of course we could take the limit of this, but we can just take the derivative of this with respect to temperature more easily.
那意味着热容，当然我们也可以做它的极限，但我们用它，对温度求导更容易些。
So let's take the derivative with respect to the temperature on the bottom first.
让我们首先，对分母做温度的微分。
OK, now I have this derivative of the Gibbs free energy divided by the temperature.
现在要进行微分，对除以温度之后的吉布斯自由能。
That is, if we take the derivative G of delta G of mixing the partial derivative with respect to pressure, at constant temperature, of course, there's no explicit pressure dependence.
就是说，如果我们对,混合物的△,对压强求导，温度不变，当然，不是对压强的显函数。
I just need to take log of it, take its derivative with respect to temperature.
我只需要取它的对数，对温度微分。
Then we can take the derivative of that quantity, when we vary the temperature, holding the volume constant.
即恒定体积，改变温度，这里恒定温度下。
