Most materials contract when going from a liquid to a solid state. This is because materials have more thermal energy in the liquid state, meaning that the molecules have enough energy to move around freely but still remain loosely bound to each other. When the material freezes, the molecules lose the thermal energy and cannot overcome the intermolecular forces, therefore staying in place and forming a rigid solid. When the molecules in the material become rigid they take up less overall space compared to when the molecules were freely moving around in the liquid state.
Water, however, is an important exception to this rule. When water freezes the individual water molecules line up with one another to form a lattice-like crystal structure. When water is in its liquid state the individual molecules were free to move around each other. When water freezes, the rigid ordering of the molecules takes up more space, resulting in greater volume but lower density. This is why ice floats and freezing a can of soda will cause the can to burst.

What do most materials do when they are cooled?
Contract.
What happens to frozen water that is different from most frozen liquids?
Frozen water expands, while other frozen liquids contract.
Does plasma expand when heated?
I assume as most materials do.
Do metal expand when it gets cold?
No. Most materials expand when they get hotter. A notable exception is water between 0 and 4 degrees centigrade.No. Most materials expand when they get hotter.

Does an iron ring expands or contracts on heating?
Most materials expand when heated.
Does a liquid expand when frozen?
No. Most liquids contract when they freeze. Water is unique in that it expands.

What do most materials do when freezing?
Contract, or become smaller.
How does something expand?
Most things will usually expand because the atoms in it get heated and force the boundaries outward. Water is the exception which expands when frozen.
What happens to most materials when it is on cooling?
Most materials solidify when they are cooling. The molecules slow down and begin to arrange themselves closer together. Some materials have an opposite reaction.
Does Ice contract when cooled and expand when heated like most other solids?
yes
What happens to material when heated do they expand contract change color double the size?
Most materials expand when heated. A few contract under certain circumstances, for instance water contracts when heated between 1 and 4 degrees C. Some change colour, e.g. zinc oxide. Whether they could double in size depends on the material and the temperature increase.
Does an iron ring expands or contracts on heating?
Most materials expand when heated.
When a concrete road is put down black asphalt stripes are placed between sections of the concrete to?
Prevent or reduce cracking of the concrete due to thermal expansion. Most materials expand when heated and contract when cooled. The strips are usually a fibrous material that allows the concrete expand and contract without breaking. Without those strips, random and irregular cracks would occur.
