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'd like, but you'd far better not-er
You can try it if you’d like, but you'd far better not-er
Cause the cold in the cooler will get hotter as a rule-er
Cause the cold in the cooler will get hotter as a rule-er
Because the hotter body's heat will pass to the cooler
Cause the hotter body's heat will pass to the cooler

First Law
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
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
Is gonna cool down
'Cause 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 a hotter
Try it if you'd like but you'd far better not-er
'Cause the cold in the cooler will get hotter as a rule-er
’Cause the hotter body's heat will pass to the cooler
Oh, you can't pass heat from a cooler to a hotter (Heat won't pass from a cooler to a hotter)
You can try it if you'd like, but you'd only look a fool-er (Try it if you want but you'd only look a fool-er)
'Cause the cold in the cooler will get hotter as a rule-er
And that's a physical law

Oh, I'm hot
Hot? That's because you've been working
Oh, Beatles nothing

And that's the First and Second Law of Thermodynamics
