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.
Well, Water Changes into a Solid...Ice.
liquid - depending on what the solid was to start with
Most plastics are actually liquids .... they are just very viscous. The glass in your window is also a liquid. A solid has a defined crystal structure. Things like asphalt, plastic, and glass don't have a crystal structure and are therefore liquids. Really think, viscous liquids. As you heat them, they become softer and softer as opposed to melting and changing to a liquid all at once.
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.
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.
Solid
Liquids become solids upon freezing. Most solids contract when they freeze. The expansion of water when it becomes ice is an unusual property.
solid, liquid then gas
liquid - depending on what the solid was to start with
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.
Solids do not mix well because there shape can not change. But a liquid and a gas can change their form. For example- you can't just change the shape of ice, but you can change the shape of water. Hope that helps
Solid iron will float in liquid Mercury. In most liquids it will sink.
With liquids you can just stick in a thermometer into it. But with solids sometimes you can't do that (because it's solid obviously) so I guess measuring liquids is more accurate in most cases.

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.
