The three + one laws of thermodynamics:
1. You can not win the the game. (∆U = ∆Q +∆W)
2. You can not play for a draw. (∆S≥0)
3. You can not leave the game. (lim t->0 ∆S=0)
And a little addition by me. I couldn’t stand it that there was nothing for the so called zeroth law of thermodynamics:
0. The game is everywhere. (If A= B and B=C then A=C)
Keep in mind that these laws are valid anytime anywhere throughout the Universe.
Enjoy your life!
