The first law of thermodynamics is a basic law. But it does NOT obey Gallalian Invariance.
This is because it deals with the kinetic energy which is not of Gallalian Invariance. This law: W+Q=(K2+P2)-(K1+P1) W: work; Q: Heat input/out to the system; K: kinetic energy; P: potential energy. You will find that the work needed is different in two inertia frame if you increase the total energy in same amount for a system. |
