The first law of thermodynamics
Heat is work and work is heat
(Heat is work and work is heat)
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 be hotter as a ruler 
('Cause the cold in the cooler will be hotter as a ruler) 
Because the hotter body's heat will pass to the cooler
 
Heat is work and work is heat 
And work is heat and heat is work 
Heat will pass by conduction
(Heat will pass by conduction)
And heat will pass by convection 
(And heat will pass by convection) 
And heat will pass by radiation 
(And 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 
Is gonna cool down as it can't increase 
Then there'll be no more work 
And there'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 a cooler to the hotter 
Try it if you like but you'd far better notter 
'Cause the cold in the cooler will get hotter as a ruler 
'Cause the hotter body's heat will pass to the cooler
 
Oh, you can't pass heat from a cooler to a hotter 
You can try it if you like but you'd far better notter 
'Cause the cold in the cooler will get hotter as a ruler 
That's the 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 thermodynamics
