Hi Icipeoples,


Say ewe had a box and ewe filled it with water then froze it then shaved off the surplus that had expanded then sealed the box so that every single side of the ice was airtight sealed and in contact with the sides of the box and then ewe seal the box and vacuumise it too !!




Would the ice melt ? Because water takes up less volume than Ice,......... if it were impossible for the volume to be reduced would this keep the ice frozen ? .........or would it just be fat water ?


What Do Ewe Think ?

Can't vacuumise it if there's no air left to pump out.
OK, ice in a perfect box, which you then heat.

Would the ice melt ?

Any melting would reduce the volume, so it would be at lower than normal pressure. At the lower pressure, the water can't exist, so some of it goes straight to gas until the pressure equalizes. At the end, there's mostly water and some water vapor under sufficient pressure to keep the bulk of it liquid.

if it were impossible for the volume to be reduced

I can't think of how you'd prevent a thing from fitting in less space. If it actually did that, there would just be not-water where it wasn't. For instance, Earth fits just fine in a cube of space much larger than Earth. It doesn't bother Earth that it's in a volume too big for it.

Thank you Halc

Perhaps the other way around, keep ice from freezing.

Excellent video. Thank you Petrochemicals

You can make stuff fit into less space by condensing steam in a gallon can. Eventually the can collapses with a satisfying bang which will be familiar to anyone who studied elementary physics before Health and Safety insisted on a Risk Assessment that required ear defenders and post-traumatic counselling.

Fortunately Trevithick and Watt invented modern industry before the bureaucrats could stop them.  Fire, steam, rotating machinery....are they completely mad?

Still wrong, 11 years later.
