摘要

在 2022 年 9 月的《物理教师》（TPT）杂志上，理查德-考夫曼（Richard Kaufman）和哈维-勒夫（Harvey Leff）展示了热力学第一定律和第二定律之间的相互依存关系。在这里，我更进一步，利用第一定律蕴含第二定律，第二定律蕴含第一定律的事实。这种双向蕴涵确立了第一和第二定律的逻辑等价性。虽然这两个定律在逻辑上是等价的（当其中一个为真时，另一个也一定为真），但这并不意味着它们是相同的。这种等价性使学生、教师和物理学家对热力学定律有了更深刻、更丰富的理解。当然，如果我们能够知道第一定律和第二定律是等价的，那么我们就应该知道。

The first and second laws of thermodynamics are logically equivalent

In the September 2022 issue of The Physics Teacher ( TPT), Richard Kaufman and Harvey Leff showed the interdependence of the first and second laws of thermodynamics. Here, I go further and use the facts that the first law implies the second law, and that the second law implies the first law. This two-way implication establishes the logical equivalence of the first and second laws. Although the laws are logically equivalent (when one is true, then the other must be true), this does not mean that they are the same. The equivalence provides for a deeper and richer understanding of the laws of thermodynamics for students, teachers, and physicists. Surely, if we can know that the first and second laws are equivalent, then we should know.
