If ice did not float it would be a far colder planet.

A physics teacher once asked what would happen if water, when freezing into
ice, became smaller as it got colder like all other materials. At the time
it seemed simple, the ice wouldn't expand so no more cracked engine blocks
and manifolds. Also docks wouldn't be lifted in winter and boats could
probably be left in the water all winter. Other than that, not much change
right? The answer was surprising! What do you think?

It only expands because as the water freezes it does so as lots of tiny
ice crystals, there is some space (small) between these crystals. Change
of state from a chemically homogeneous liquid (H2O) to a tightly packed
lump of solid (ice) crystals

So a kg of ice has a larger volume than a kg of liquid water, that's
why it floats.

Whenever water freezes the ice crystals no matter how tightly packed
have to take up more volume than the water did & oops the cast iron
engine block just can't accommodate a volume increase of say 5-10%.

That dumb uneducated lying idiot Krause has for years argued here that
a timber boat of the same weight as boat of any other materials, will
"float" higher in the water because... wait for it....wait....... wood
floats!!!:-)

Hey! Didn't you read about the truce? This is becoming a peaceful and
harmonious group. There are still a few who haven't gotten the word,
but they're working on it!

Well, among other things, ice would sink. The end result could be, no
more northern lakes, as the ice would fill them, and only the top layer
would thaw.


Kind of a reverse turn over only permanent.

Interesting.

The way I was told the ice wouldn't form at the surface and thus insulate
the water below from freezing. Oceans and lakes would freeze from bottom up
due to the denser ice sinking. The ice caps would grow larger. Lakes
wouldn't completely thaw in summer. The growing area of ice would reflect
sunlight, further cooling the earth to a point where the planet would be
uninhabitable. All water would soon be ice. I'll admit there may be holes
in the theory somewhere though.


Makes sense.

Later,

Tom

Yes I read John:-) Sorry but Harry has done this before too, he'll
still & has even since then, started OT threads & he'll continue his abuse.

It suits him right now John, after the election postings etc, I best
tell you there's been a slight change???? some of the "anon" news access
points have recently been closed (cut off by proper news servers more
accurately), they along with the X no archive yes headers, were mainly
used by the mentally ill, apparently doctors & law enforcement people
were using their behaviour in NGs as evidence:-) Needless to say the
liar Krause was a user of such devices not withstanding his protests to
the contrary (he would wouldn't he? he's a liar:-)). So now he has to
tone it down because he's stuck using the public news servers again & I
would have great pleasure I can assure you in having him chucked from
them one after the other. I see it as electronic stoning which is
probably too good for him:-)

I have been in OT posts & it's rare (very rare?) that I'll start one
(although I admit to same on occasion:-)), if that's your concern be
assured I'll not be starting any OT threads while your truce is in play,
however I reserve all my rights & remedies as regards the lying grub Krause.


Sorry if this upsets you John because I think you do a sterling job of
standing up to Krause's socialist simpleton tribe & I count you as one
of the NG bricks, keep up the good work & don't get conned by him......
again:-)

Sorry, babe, but that sweet approach isn't going to work, either. You'll
have to stuck to diddling yourself with that Louisville Slugger and
five-gallon jug of K-Y.



Er, stick. Mo' betta'


Thanks for the correction creepy krause I hadn't fully got the message
first time:-)

There would be no life on earth so boats wouldn't be significant. Every
body of water including the oceans would be frozen all the way to the
bottom, perhaps thawing a thin layer on the top during the warm weather.
