In physics the heating described by Boyle's law is a consequence of work, typically the kinetic energy imparted to molecules by a compressor.
A temperature increase resulting from compression is a temperature increase resulting from friction. In other words, it's friction all the way down (until it's electromagnetism and other fundamental forces).
- pfdietz 6y agoNo. Isentropic compression is reversible; friction generates entropy and is not.
- rz2k 6y agoThe "compression" in front of a de-orbiting satellite does generate irreversible entropy, and the physicists are correct to say that air friction causes the heat during reentry.
- pfdietz 6y agoRight. The argument that the heating is by compression is at best misleading, and at worst completely wrong. The dissipative process in the shock is more akin to friction.
- rz2k 6y agoHmm, that is what I was getting at in this thread. The other user claimed that physicists are making a mistake when they explain with friction rather than compression. Looking back, I think your first comment was meant for the other user.
