When I think back to my High School Physics (a couple of hundred years ago) I do recall learning that it takes 80 times as much energy to change state than it does to change the water temp. 1 degree C. Not sure if that has f**K all to do with this. :lol:

There is a prize available for anyone who can determine why it works in some cases and not in others:
Why does hot water freeze faster than cold water?

Definitely..............................the added bit of knowledge! :lol::lol:

Well, there's a huge difference between putting warm water in a unit with refridgeration and a set point than there is with warm water in the Arctic.

When you put warm water in the freezer it raises the temperature inside the freezer above the set point, and then the refridgeration kicks in to bring the temp down. With the unit running, warm water will cool faster than cold water.

If you put a cup of warm water and a cup of cold water in an ice bath, the cold water will freeze first. It's not a special property of water, it's a property of refridgeration units that allows warm water to freeze faster.


Wrong, but that's ok, you can't be right all the time, and with keeping with the likes of cabbage and redmonton, I won't bother supplying a link to back myself up. You'll just have to take my word for it because I am smarter than you. ;)

Oh he has a point, and it may apply in some way. But I highly doubt it applied to sea ice.

While I was researching the Mpemba effect, I came across something that I could have sworn I read before, and low and behold...

It's customary to post a link or accreditation when you quote other peoples work...

Why does hot water freeze faster? And other cracking science mysteries | Philip Ball | Comment is free | guardian.co.uk

Passing off other peoples work as your own, is called plagiarism, and it's frowned on here at CC. It also puts the site at risk.

Ya right,want me to dig up all your instances of copyright infringement?

And in case you did not know,most arctic ice is fresh water,not saltwater.

Maybe you should google before hitting send with info and claims on a place in Canada you have no clue about.

So if warm water freezes faster then cold water(fresh water for cdn bear who has no clue whats in the arctic)then the ice should start building sooner each year,mother nature taking care of herself.
North of Hudsons bay,im my experience doing ice profile for ice roads,we built an inch a day after december 30th in ice thickness.

Nuna engineers will confirm this.They are the experts in building Arctic ice roads.

No link because i'm talking from experience here.

Say what? I think you really need to back this statement. Considering "arctic ice" is frozen Arctic Ocean. It's not the same as Glaciation of Greenland, or the Ice Shelf in Antarctica.

Go for it.

Better yet, why don't you go find posts I've made where I post other people work as it were my own.

Pack ice is what?

That's your thing, not mine. You should try and do a better job at it though.

That would explain why you need to post unaccredited material.

Damn you beat me to it! lol.

Jheeez,wonder where it comes from? North maybe? Like the Arctic?
It cant go into the ground because of the permafrost.

The Great Lakes are the largest system of fresh, surface water on earth, containing roughly 18% of the world supply.

What does that have to do with the Arctic Ocean?

Go tell someone who cares,your not even worth trying to answer anymore.

Some of you folks should take the advice of some other members and mods and attack the message and not the messenger.

Unless you got nothing then by all means go for it.
Some folks need to figure out this is a discussion forum,a lot of you are worse then the politicians in question period,grow up if you want to discuss issues.

Those are questions, not statements.

Maybe the fact that I keep pointing out your glaring errors and mistakes, is the reason you think I'm not worth answering.

Seems to be a common trait amongst the same type of members here, lol.

Problem is, when the message gets questioned, some messengers tend to take it personal and attack/bully/make accusations/stalk etc....
I'm looking forward to seeing what he digs up in the way of me posting unaccredited works of other people.

Your not worth the time actually,I was just saying I could,I'm sure most of your jpg images are borrowed.

I never passed anything off as my own either that wasent mine,you really are scraping the bottom of the barrel to dirt me,what a loser.

The bulk of them are, which is why I post them by link to the original source.

But that's not really in context is it?

I don't pass off others articles as my own, do I?

You should back up your claims if your going to start assuming.
Sorry but I quote from experience,not google or wiki.

And another thread dirtied up by the resident Can Con troll.
I guess you dont want to debate anything eh?

Too funny!
