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.

∙ 9y agoOne gallon of water will expand to be about 1.09 gallons of ice. This is because ice does not expand that much.
Wiki User
∙ 8y agoIt happens because of the breaking of hydrogen bonds between the water molecules. An example is when ice is heated (turning it to water).

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

∙ 11y agono in general. Ice and a few other materials expand as they freeze, but most materials shrink when cooled. The reverse when they warm.

Wiki User
∙ 12y agoYes. 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.

Why is energy absorbed when ice melts?
When an ice cube gains energy, it is the same as gaining heat. So if an ice cube is getting warmer, it melts.
Does ice melts or dissolve in water?
Ice melts in water because the ice is below freezing and the water is above freezing (warmer than the ice) so slowly the ice melts in the water, but still cools it down a little. when it melts the water frozen in the ice form is added to the amount of water it was put in.
When ice cream melts do the particles in the ice cream move slower?
When ice cream melts, the particles actually move faster, not slower, then when it is unmelted.
Why does soda melt ice?
the ice just melts its self
Ice melts at?
The traditional melting point of ice is 1 degree C, but anyhting above 1C should do the trick.
When ice melts does it expand?
yes it does. one of the consequences of water due to hydrogen bonding.
Does Ice contract when cooled and expand when heated like most other solids?
yes
Does water continue to expand as it cools after forming ice?
Water expands when it first freezes, but after that ice will contract as it continues to cool.
What property changes when a ice cube melts?
When an ice cube melts, heat is transferred from the external environment to the frozen water, causing the molecules to move more quickly. The moving molecules contract, forming liquid water.
Why wouldn't it be sensible to put an ice cube in a vacuum flask?
When water freezes becoming ice it expands. In a vacuum flask as ice melts it will contract. This will cause the flask to crack.
What is in salt that melts ice?
It is the salt itself that melts ice.
Will the jar contract or expand when heated?
Heat would cause the molecules to speed up movement and expand metals. Glass melts, paper burns, clay would shrink as water vapor escapes, etc.
Where does the white go when ice melts?
The white doesn't go anywhere when ice melts. When ice melts, its turns into water. Ice is just frozen water.
What is colder snow or ice?
Ice because I know that snow melts ice.And why does snow melts ice???
Is level of water increases when ice melts over it?
Ice in its frozen state has agreater area than liquid water, however as ice melts it does expand, before returning to its smaller area. Water is unique in that it expands when freezing, and again when melting (thus bursting water pies) but does not reatin the volume as a liquid.
What changes when ice cubes melts?
a ice cube melts when it heats up
What ice becomes when its melt?
When ice melts it becomes WATER!
