Starcoaster Posted February 11, 2012 Report Share Posted February 11, 2012 Oh Godddd. No I have not. Is this hypothetical, or is this what is about to happen to you when it thaws? Link to comment Share on other sites More sharing options...

Don't panic, your boat doesn't get to stand long enough for the cold too creep in enough. Tawny Owl has never spilt a tank, even after cold soaking for a fortnight Richard Link to comment Share on other sites More sharing options...
steven wilkinson Posted February 11, 2012 Report Share Posted February 11, 2012 surely the tank would need to be quite, or completely, full or the expansion due to freezing would just be vertically into the void of the tank! Link to comment Share on other sites More sharing options...
luctor et emergo Posted February 11, 2012 Report Share Posted February 11, 2012 The splitting whilst frozen is a nuisance, the roblem doesn't start until it thaws... Link to comment Share on other sites More sharing options...

Tanks or pipes do not burst when they freeze. They burst when they thaw! Link to comment Share on other sites More sharing options...

Wrong! they can burst,bust,split, crack and de joint when they freeze, you only see it when they thaw. Link to comment Share on other sites More sharing options...

bottle Posted February 11, 2012 Report Share Posted February 11, 2012 Ian and Ali Chill (pun intended), reading some of your recent posts, you do seem to worry about what might happen. They probably never will and if they do, you will deal with them. Relax and enjoy your boating. Link to comment Share on other sites More sharing options...

Like everything else, when water gets colder and freezes, it shrinks. When it gets warmer, it expands, producing the pressure that causes the fracture.

steven wilkinson Posted February 11, 2012 Report Share Posted February 11, 2012 really? I was under the impression that yes water cools and contracts, but when it freezes it expands significantly. So the expanding freezing ice bursts the pipe, but as its solid it doesnt leak, but when it thaws out, the water leaks through the now-split pipe!

Sorry Brian - - - But when water freezes it expands - (and splits the pipes etc) when it thaws - you notice the split Edited February 11, 2012 by Grace & Favour Link to comment Share on other sites More sharing options...
P R Posted February 11, 2012 Report Share Posted February 11, 2012 Like everything else, when water gets colder and freezes, it shrinks. When it gets warmer, it expands, producing the pressure that causes the fracture. Yes water does expand when heated, and contract as it cools, but it then expands as it freezes. The pipework however can handle the presure of heated water(to a point!) as it also expands when hot, but then contracts when cold so the presure from the frozen water has knowhere to go and fractures the pipe or fittings.

Ok I stand corrected, water apparently behaves differently fom other liquids when it gets below 4 degrees C. I must have skipped that chemistry lesson! I am duly humbled.

I must have skipped that chemistry lesson! I am duly humbled. Water also freezes from the outside of a pool towards the middle. If it didn't do that, and behaved like other liquids, there would have been no life on Earth. Link to comment Share on other sites More sharing options...
dmr Posted February 11, 2012 Report Share Posted February 11, 2012 The 4 degree turn around is (i think) called the "anomalous expansion of water". O level physics was a while ago. We went to Saul festival before owning a boat (drawn by the music) but walking the canal we met an old brummie boat owner, well into his 70's and full of stories. One was about a split poo tank and the only solution to the lingering smell was to get a new and bigger boat. Another story was that after his doctor told him to stop smoking weed (about a pound each week) his otherwise perfect health had gone downhill!!!!. We thought we like these people...lets get a boat and join them! ..........Dave Link to comment Share on other sites More sharing options...

ETA see this has already been covered. Edited February 11, 2012 by Biggles Link to comment Share on other sites More sharing options...
Higgs Posted February 12, 2012 Report Share Posted February 12, 2012 Water is more dense than ice and ice floats. For a given volume of water, to get it to float on itself it has to expand into a larger size that contain more space (air) between the molecules (ice). I think.

jelunga Posted February 13, 2012 Report Share Posted February 13, 2012 Can anybody explain the triple point of water? It is apparently the temp at which water can exist in 3 states- solid(ice) liquid and vapour (steam). Link to comment Share on other sites More sharing options...
