The first law of thermodynamics
Heat is work and work is heat
(Heat is work and work is heat)
Very good

The second law of thermodynamics
Heat cannot of itself pass from one body to a hotter body
(Heat cannot of itself pass from one body to a hotter body)
Heat won't pass from a cooler to a hotter
(Heat won't pass from a cooler to a hotter)
You can try it if you like but you far better notter
(You can try it if you like but you far better notter)
'Cause the cold in the cooler will get hotter as a ruler
('Cause the cold in the cooler will get hotter as a ruler)
Because the hotter body's heat will pass through the cooler
(Because the hotter body's heat will pass through the cooler)
Oh! First Law
Heat is work and work is heat (Heat is work and work is heat)
And work is heat and heat is work (And work is heat and heat is work)

Heat will pass by conduction
(Heat will pass by conduction)
Heat will pass by convection
(Heat will pass by convection)
Heat will pass by radiation
(Heat will pass by radiation)
And that's a physical law

Heat is work and work's a curse
And all the heat in the universe
It's gonna coooool down as it can't increase
Then there'll be no more work
And they'll be perfect peace
(Really?)
Yeah, that's entropy, man!
And all because of the second law of thermodynamics, which lays down

That you can't pass heat from the cooler to the hotter
Try it if you like but you far better notter
'Cause the cold in the cooler will get hotter as a ruler
'Cause the hotter body's heat will pass through the cooler
Oh, you can't pass heat from the cooler to a hotter
You can try it if you like but you'll only look a fool
'Cause the cold in the cooler will get hotter as a ruler
That's a physical law
Ooh, I'm hot!
(What? That's because you've been working)
Oh, Beatles? Nothing!

That's the first and second law of thermo-dynamics
