通过分解 q，我们得到了下面的形式，正如克劳修斯所推导的:

Thus, for example, if Q was 50 units, T<sub>1</sub> was initially 100 degrees, and T<sub>2</sub> was initially 1 degree, then the entropy change for this process would be 49.5. Hence, entropy increased for this process, the process took a certain amount of "time", and one can correlate entropy increase with the passage of time. For this system configuration, subsequently, it is an "absolute rule". This rule is based on the fact that all natural processes are irreversible by virtue of the fact that molecules of a system, for example two molecules in a tank, not only do external work (such as to push a piston), but also do internal work on each other, in proportion to the heat used to do work (see: Mechanical equivalent of heat) during the process. Entropy accounts for the fact that internal inter-molecular friction exists.

因此，举例来说，如果 q 是50个单位，t1 / sub 最初是100度，t2 / sub 最初是1度，那么这个过程的熵变为49.5。因此，这个过程的熵增加了，这个过程需要一定的“时间” ，并且熵增加与时间的流逝相关。因此，对于这种系统配置，它是一个“绝对规则”。这一规则是基于这样一个事实，即所有的自然过程都是不可逆的，因为一个系统的分子，例如一个罐中的两个分子，不仅做外部功(如推动活塞) ，而且根据过程中所用的热量(见: 热量的机械等效物)相互作内部功。熵解释了分子间存在内部摩擦的事实。
