Thermodynamics

The First Law of Thermodymamics:

Heat is work and work is heat

Very good!

The Second Law of Thermodymamics:

Heat cannot of itself pass from one body to a hotter body

(scat music starts)

Heat cannot of itself pass from one body to a hotter body

Heat won't pass from a cooler to a hotter

You can try it if you like but you far better notter

'Cos the cold in the cooler with get hotter as a ruler

'Cos 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 convection

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 cooool down 'cos 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 the cooler to the 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 from the cooler to the hotter

You can try it if you like but you'll only look a fooler

'Cos the cold in the cooler will get hotter as a ruler

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 Laws of Thermodynamics!"
