Ageing in this case must occur according to the laws of physical chemistry and of thermodynamics.
在这种情况下，老化必须根据物理化学和热力学定律进行。

This, in a nutshell, is the second law of thermodynamics, which states that the entropy (a measure of the disorder) in a closed physical system never decreases.
简单来说，热力学第二定律表明在一个封闭的系统中，熵是不会降低的。
