Three states of matter. Solid, liquid and gaseous. Of course there is a fourth state called ionic state of matter.
In solid atoms or molecules are well packed and they form mostly crystal structure.
In liquid, atoms or molecules or ions will be in random motion.
In gas, the motion will be severe and the attraction between atoms or molecules or ions will be almost negligibly small.
So when liquid is changed into solid the free roaming atoms or molecules will be arrested and they are bound to form lattice and start to have lattice vibrations.

The most common indicators of a chemical reaction are: 1. A color change. 2. A temperature change. 3. Bubbles (indicating a gas) 4. A precipitate (a solid that settles out of liquids) A chemical change can feature all, none, or any combination of these.
The density of solid state of matter is higher than the density of liquids and the density of liquids is higher than the density of gases.
The density of solid state of matter is higher than the density of liquids and the density of liquids is higher than the density of gases.
Water has a lower density as a solid than it does as a liquid. In the vast majority of substances are denser as solids than as liquids.
Most liquids become solids through a process called freezing. During freezing, the molecules in the liquid slow down and come closer together, forming a solid structure. This process typically occurs when the temperature of the liquid is lowered below its freezing point.
Many solids will change into liquids if you heat them, for instance most metals will melt when subjected to heat, ice will become water when heated, some plastics will melt, glass will melt, and most rocks will also melt.
Liquids become solids upon freezing. Most solids contract when they freeze. The expansion of water when it becomes ice is an unusual property.

When most liquids change to their solid state, they become denser. However, water freezes and the resulting solid, ice, is less dense than it's liquid state (aka ice floats over liquid water)
The physical properties are of course different.
No, cooling solids typically causes them to contract and become denser, rather than changing into gases. Cooling a substance lowers the kinetic energy of its molecules, which reduces the distance between them and causes the solid to solidify further. However, if the solid sublimes (changes directly from solid to gas), then cooling could cause it to transition into a gas.

temperature. The higher the temperature of the liquid, the more of the solid you can dissolve in it.
Most solids become liquid at their melting point. Heat water above 0°C, or iron above 1,535°C, and they will become a liquid.
