The First law of Thermodynamics.
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 won't pass from a cooler to a hotter
You can try it if you like but you'd far better not-a
'Cos the cold in the cooler will get hotter as a rule-a
'Cos 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 and
Heat will pass by convection 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,
'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 a cooler to a hotter
Try it if you like but you'd far better not-a
'Cos the cold in the cooler will get hotter as a rule-a
'Cos the hotter body's heat will pass to the cooler
Oh, you can't pass heat from a cooler to a hotter
Try it if you like but you'll only look a fool-a
'Cos the cold in the cooler will get hotter as a rule-a
And that's a physical law That's because you've been working!
Oh, Beatles, nothing!
That's the first and second laws of thermodynamics. (TA DA!))
That's the first and second laws of thermodynamics. (TA DA!))
A compelling argument, on the surface. But you're forgetting something:
The sun is a mass of incandescent gas
A gigantic nuclear furnace
Where hydrogen is built into helium
At a temperature of millions of degrees
Yo ho, it's hot, the sun is not
A place where we could live
But here on Earth there'd be no life
Without the light it gives
We need its light
We need its heat
We need its energy
Without the sun, without a doubt
There'd be no you and me
The sun is a mass of incandescent gas
A gigantic nuclear furnace
Where hydrogen is built into helium
At a temperature of millions of degrees
The sun is hot
It is so hot that everything on it is a gas: iron, copper, aluminum, and many others.
The sun is large
If the sun were hollow, a million Earths could fit inside. And yet, the sun is only a middle-sized star.
The sun is far away
About 93 million miles away, and that's why it looks so small.
And even when it's out of sight
The sun shines night and day
The sun gives heat
The sun gives light
The sunlight that we see
The sunlight comes from our own sun's
Atomic energy
Scientists have found that the sun is a huge atom-smashing machine. The heat and light of the sun come from the nuclear reactions of hydrogen, carbon, nitrogen, and helium.*
The sun is a mass of incandescent gas
A gigantic nuclear furnace
Where hydrogen is built into helium
At a temperature of millions of degrees
