Here is a song by
Flanders and Swann recorded many years ago that explains the laws of thermodynamics very clearly. Â They say:
The First Law of Thermodynamics: Heat is work and work is heat
That is all there is to it really.
Then they sing,
The Second Law of thermodynamics: Heat cannot by its self pass from one body to a hotter body
Then they go on to jazz it up…
That’s entropy man
