Get in the queue smart arses - I have a magic freezer!

[Mom]

Even the most simple of us know that liquids expand when they are frozen. In my experience water contracts when it freezes

How many of us have forgotten a bottle of something in the freezer for a quick chill, and found the countainer exploded in the freezer? In my freezer it gets smaller.

I drink water through the day. I wont drink the stuff that passes for water in Albany I wont spend money, buying something I already pay for at home. It pretends to be water, and I filter it to exclude the chlorine and aluminium that it contains.

I freeze my filtered water in a bottle at home and take it to work to drink.

So, I half fill a 1.5l bottle with filtered water and I screw the lid on the bottle. I place it in the freezer, on its side so it freezes by morning. The bottle is "normal" bottle shape when it goes in, and quite distorted when I take it out. "Flat" springs to mind. I top it up with filtered water, and by the time I get to work and want a sip of refreshing water, the bottle makes a distinct intake of air sound and regains its "normal" appearance when I open it.

Please explain!

Water does expand,
Thats why ice doesnt sink.. It's density is less than the liquid water around it.

[bogan]

Water expands a little, air contracts a lot more = smaller

[DrunkenMistake]

If I remember right, between 4 degrees and 0 degrees water contracts but below 0 it expands, by 9%

bottle on side in freezer, half full of water, sealed, yes?

as water freezes it expands, as it expands it compresses the air above it and as it expands it distorts the shape of the bottle. when you open the bottle the pressurised air comes out. You top it up and the laws of thermodynamics being what they are, the ice melts. the melting ice turns to water which shrinks. if there is an air gap the air pressure would decrease as the water volume decreased, if no air gap the bottle shape will distort, perhaps not so much you can see it. either way, when you open the top, the pressure equalises air comes in to fill the void, and thats the noise you hear.

or its the gnomes in your carbs getting thirsty. thats probably more likely. one or the other

not only have you frozen the water but you have also frozen the gas in the remaining half of the bottle and the plastic of the bottle. On its way to frozen the water does contract, as it turns to ice it expands. The contracting water, gas and plastic squash the bottle. The plastic freezes in this shape, it therefore remains squashed as you top it up with water and the frozen air escapes. When you open it at work the plastic defrosted, so has some of the ice therefore when you open it the plastic is going ot 'bounce' back to shape sucking in air.
How's that for a guess.

Id say its the Gnomes.

[Clockwork]

I think its the air inside the bottle that has contracted.... not so much the water.

[Headbanger]

So, your magic freezer......freezes water.

Awesome.


Though I think most of them do that.




If I had a magic freezer I'd want it to be full of unlimited steak and cheese pies, and they would be served up hot and tender, and it wouldn't need electricity, and it would fit in my pocket.

And I'd get $10 for each pie I ate.

Fuck yeah, thats a magic freezer worth owning.

[crystalball]

I am thirsty now.

If you think that your filter is removing the chlorine from tap water, it must be a helluva good filter. Many water filters sold in New Zealand come from Dodgy Brothers Ltd and are sold by homeopaths or similar flat earthers.

Chlorine is added for good reason: it's a disinfectant. You can only smell it when it's disinfecting. I'm not sure where the aluminium you think is in there has come from.

That said, I am fascinated by what's happening to your imploding bottles in your freezer.

Ah, No. Exactly the opposite.

When a liquid reduces to a solid, the molecules slow down and form a crystalline structure. Solids are always smaller versions of their liquid form.

Except water. It has the remarkable ability to expand. http://www.iapws.org/faq1/freeze.htm

[avgas]

You think that's water you are drinking?

[BMWST?]

water is at it most dense state at 4 c,as it actually freezes it forms an open crystaline structure.
