When ice melts does it expand or contract?

Answer 1

When water turns from water into ice, it actually does expand. Depending on the salinity of the ice, it will however contract slightly (if fresh water) or it will expand slightly and then contract (as the temperature lowers). You'll notice that if your freezer is too cold, the ice cubes in the trays will actually have cracks in them, this is an example of the relief of internal pressure created by the contraction.

Answer 2

When ice melts, it contracts and decreases in volume. This is because the water molecules in ice are more spread out than in liquid form, leading to a decrease in density when it transitions to water.

Answer 3

It contracts because the increase thermal energy causes the hydrogen bonds to be shaken out of position. This weakens the hydrogen bonding and allows for less space in the liquid structure. Therfore, when ice melts in contracts. This is also why liquid water is more dense than ice.

Answer 4

One gallon of water will expand to be about 1.09 gallons of ice. This is because ice does not expand that much.

Answer 5

It happens because of the breaking of hydrogen bonds between the water molecules. An example is when ice is heated (turning it to water).

Answer 6

When water turns into ice its volume increases 9%.

After that the ice does not expand as it gets colder. In fact it contracts a very small amount.

Answer 7

no in general. Ice and a few other materials expand as they freeze, but most materials shrink when cooled. The reverse when they warm.

Answer 8

Ice is one of the only known substance that contracts when it melts

Answer 9

Yes. The reason that ice floats in liquid water is that a mass of frozen ice takes up a little more volume than the same mass of liquid.

Answer 10

When ice thaws the molecules expand.
