A Difficult Question / ChiroVette's Question Time - Page 5

quote Randome

Well, that was a trick question to begin whit ...and since you're tho only one who even tried, then you go next.

So you're really not convinced that I'm right? You sounded like "meh"...

And I don't know of any good question to which I do not know the answer of other than rhetorical ones. So someone else may post his.

Two possible reasons:
1: In some countries (not here) it's just that dirty;
2: It's full of little bubbles, which decrease the waters transparency.

quote The Haz

Usually it's warm when it's cloudy.

No idea why though

Maybe because the heat from the sun or a water heater caused the water to evaporate (and please note that water does not necessarily need 100^oC to evaporate). Since the vapour has nowhere to go while in the piping I guess it stays in the water.

Another plausible theory is that the filter in the tap causes the streak of water to break up into many thin streaks. These thin streaks fuse again at some parts (due to water molecules attracting) thus trapping some air which causes the bubbles. Like this:



Although air and water are both colourless, the light rays refracting many times causes the image behind the water to become very distorted, so the white colour you see is roughly the average colour of the image behind the water.

By the way; is the phrase "streak of water" correct?

quote Randome

I think it's "stream of water" and you're answer is probably right.

Stream is a different thing. I meant "streak" as in "streak of lightning".

I'll let someone else.

What do you mean?

Like when you eat, sometimes a bit of puke comes out with a burp, but only a bit
