What is the sound when you boil water?

If you put a kettle on a high flame, it makes something of a roar. What exactly causes the sound?

@Banana Breath,
It's caused by the spiritual manifestation of the British Lion reminding you that steam power was fundamental to the ascendancy of the British Empire, despite the fact that the tea break was instrumental in its fall !

@Banana Breath,
The sound is of rapidly expanding metal as you realise that you forgot to put any water in it.

When the water starts to boil my kettle starts to whistle. Why?

@Banana Breath,
When you put cold water on a hot burner, you get nucleate boiling (small bubbles forming on the bottom surface of the kettle) but the bulk liquid is still cold, so the bubbles form, rise up and collapse as they cool off. That is what gives you that characteristic sound.

@engineer,
Engineer´s answer is correct, and yet someone thumbed him down. Apparently answering questions correctly is frowned upon here...

@Lordyaswas,
Not now... that would make my post look foolish! I don´t think Engineer cares, and I am trying to make the point.

I shall now have to thumb him down myself to counteract Lordy.

@maxdancona,
Can one extract one's thumb when it is already up someone?

@Lordyaswas,
All depends how experienced with thumbs that someone else is.

Now I'm scoring more than engineer!...... and he is the only one who knows what he is talking about.

Do you think I will win that red ribbon thingy now?

@Lordyaswas,
That's a good question, Lordy. I don't know.

But I do know that in real life we have two thumbs.
