三、绝对熵(Absolute Entropy) 一个体系的熵值直接与物质的熵值有关。由于熵是混乱度的量度,在1atm 、25℃ 时,我们就不能认为单质的熵为零,因为在此条件下,...

We looked at pressure change before, actually, in discussing the third law, the fact that the entropy goes to zero as the absolute temperature goes to zero for a pure,perfect crystal.
在讨论热力学第三定律的时候,我们讨论过压强变化,即对于纯净的完美晶体,随着温度下降到绝对零度熵也变成零。
There is an absolute zero of entropy, and that's really what we learn.
而熵是有绝对零点的,这就是我们学到的。
Last time we reach the third law which is telling us that we can't quite get to zero degrees Kelvin .but that as the temperature approaches zero degrees Kelvin, the absolute entropy of a pure substance in perfect crystalline form is zero.
上次课我们得到了热力学第三定律,这个定律告诉我们我们无法,达到0K的温度,但是在我们接近绝对零度的过程中,以完美晶体形式存在的纯物质的绝对熵,也趋向于零。
