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。
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.
前提是系统要孤立。在热力学行话中,混乱程度叫做熵。第三定律断言,没有一个系统能达到绝对零度。
As long as the system is isolated. In thermodynamics jargon, randomness is called entropy. The third law states that no system can be reduced to 0 K.
