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'd far better notter,
You can try it if you like but you'd far better notter
'Cos the cold in the cooler will get hotter as a ruler,
'Cos the cold in the cooler will get hotter as a ruler
'Cos the hotter body's heat will pass to the cooler,
'Cos the hotter body's heat will pass to the cooler
Good, 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
And heat will pass by convection,
Heat will pass by convection
And 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 cooooool down
'Cos it can't increase,
Then there'll be no more work
And there'll be perfect peace
Really?
Yeah, that's entropy, maan!
And its 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 like but you far better notter,
'Cos the cold in the cooler will get hotter as a ruler,
'Cos the hotter body's heat will pass to the cooler.
Oh you can't pass heat, cooler to a hotter,
Try it if you like but you'll only look a fooler
'Cos the cold in the cooler will get hotter as a ruler
And that's a physical Law!
Oh, I'm hot!
Hot? That's because you've been working!
Oh, Beatles - nothing!
That's the First and Second Law of Thermodynamics!
