When water is a liquid, the molecules mix around very closely to one another. Each molecule is attracted to other by forces called hydrogen bonds. These bonds keep the molecules close together but not permanently fixed in one place. As one molecule moves past another it will break old hydrogen bonds and form new ones, with different water molecules. As water cools, the molecules slow down, and can get closer together. At 4 degrees Celsius (about 39 degrees Fahrenheit), water molecules are as closely packed as they can get. When water is cooled below 4 degrees Celsius, the individual molecules start to arrange themselves into a more stable form. At 0 degrees Celsius (32 degrees Fahrenheit) and normal atmospheric pressure, water will form the stable solid we call ice. Ice, like most other pure solids, has a crystalline structure. This means that the atoms are organized in a simple repeating structure, such as a cube or a tetrahedron. The crystalline structure of ice is a repeating arrangement of eight molecules of water. This arrangement is actually less dense than liquid water at 4 degrees Celsius! There are more molecules in the same amount of space in the cold liquid than there is in the solid form. This is a very unique property of water, as most chemicals have solid forms that are denser than their liquid forms. The arrangement of hydrogen and oxygen atoms in water results in this and other special chemical properties.
solids;there molecules are closer together
When gallium melts, it undergoes a phase change from a solid to a liquid without changing its chemical composition. Gallium does not have allotropes in the liquid state; instead, it remains the same elemental form in both solid and liquid phases.
The solid that forms from liquid reactants is called a precipitate.
Rain is liquid Ice is solid. with water when you cool it (slow the molecules) it expands (which is unique to water) becoming a solid crystal, and since it expands its mass per volume ratio has changed making it less dense then liquid water.
An iceberg floats because it is less dense than the water it displaces. When ice forms, it expands and becomes less dense than liquid water, allowing it to float. This buoyancy force counteracts the downward force of gravity, keeping the iceberg afloat.
The most significant thing about water is that is expands when it turns from liquid to a solid. Nothing else has been observed to do this.
An Amorphous solid
A liquid.
When a solid forms from a liquid mixture, that is a precipitate, unless the liquid is in the process of freezing, in which case it is a phase change.
There are three main forms of water: liquid, solid (ice), and gas (water vapor). The transition between these forms is influenced by temperature and pressure conditions.
they can take different forms, the forms at liquid solid and gas.

All forms of matter have the three basic forms of solid - liquid - gas. Therefore, every solid can eventually be formed into a liquid by heating it up.
All substances can exist in solid, gas, liquid and plasma forms as well as forms in-between.Answer: Anthracite can be any.

It expands. Most substances contract on freezing.
