It only expands because as the water freezes it does so as lots of tiny
ice crystals

It's not quite that simple. Water at 1c is actually smaller than it is a 4c,
the most dense state.
That is the answer to the question "what is the temperature of of the water at
the bottom of a pond that is frozen on top". (in case you get that on your
physics test)

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!

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:-)

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

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.
