when water starts to freeze its reducing in energy?

Question

so were does the energy come from for water to increase in size ann break the pipes it travels in

Answer 1

When temperature drops into 0oC, pure water starts to build a network of H2O molecules. Referring thermodynamics, this solid form of water contains less energy because the molecules are in a better order in ice than in liquid form. This shows that the transformation of water from liquid into solid form is beneficial in 0oC.

A certain volume of water needs more space in the form of ice than in the form of liquid, however. Because the tendency of water molecules to be in a closer connection is so strong, the expanding water really has such a pressure that it can even break stone or metal pipes.

These phenomenons can be observed here in Northern Europe every year, both in our lakes and water pipes. Water did not run out of the pipes just during the heaviest colds (even -40oC sometimes!) but immediately when temperature rises. We have, therefore, be aware of pipe leaks just after the coldest periods when the icy blocks in the pipes start to melt....

Answer 2

When water freezes, it compresses and reduces in size. When A water pipe bursts it happens when the water thaws. this happens because the frozen water reverts back to a liquid form and is a larger volume that when it was frozen. As it thaws, it has to find a way out for its increased size, and in doing so, it bursts a pipe at its weakest point. There is no loss of energy when it is frozen or in liquid form.

Answer 3

The energy in freezing water is still substantial, of course.

I remember way back in the Paleocene epoch, studying chemistry and physics, that water molecules push each other apart during the freezing process, to form voids in the mass of ice (these are submicroscopic, as I recall), which accounts for the increase in volume of ice versus it's liquid counterpart.

If this is correct, then the energy comes from molecular forces (repelling of like forces??). All of this might relate to the polar nature of water molecules--one end of a water molecule has a positive charge, the other end negative. If the negatives and positives line up then eventually there will be negatives next to positives, and these will repel one another.

Answer 4

Water continues to contain energy all the way down to absolute zero. Some of that energy, upon phase transition from liquid to solid, is used in establishing the latiice-size in ice, which translates to the expansion.

Answer 5

Water expands when it freezes simply because oxygen is less soluble in water the colder water gets below room temperature. As the water freezes the oxygen gas comes out of solution, thus increasing the volume of the water hence making it less dense and thus ice floats in water.

Answer 6

It increases in size when it freezes.

Answer 7

yes, the molecules move more slowly and are producing less kinetic energy...the expansion comes from them solidifying together and not moving around as much.
