摘要

我们研究了一个教科书上的例子，它涉及对自由膨胀的理想气体进行再压缩，从而导致违反热力学第二定律。虽然这个例子从根本上说是正确的，但它在考虑将系统中的所有元素恢复到初始条件方面有些不完整。本文将对这种情况进行更详细的研究。

Recompressing a freely-expanded ideal gas and violating the second law of thermodynamics

A textbook example involving recompression of a freely-expanded ideal gas which leads to a violation of the second law of thermodynamics is examined. While the example is fundamentally correct, it is somewhat incomplete in its consideration of restoring all of the elements of the system to their initial conditions. The situation is examined in more detail in this paper.

期刊介绍： Physics Education seeks to serve the physics teaching community and we welcome contributions from teachers. We seek to support the teaching of physics to students aged 11 up to introductory undergraduate level. We aim to provide professional development and support for teachers of physics around the world by providing: a forum for practising teachers to make an active contribution to the physics teaching community; knowledge updates in physics, educational research and relevant wider curriculum developments; and strategies for teaching and classroom management that will engage and motivate students.
