View source for Solid (state of matter)

A '''solid''' is one of the main states of matter. Solids are made up of atoms or molecules that only move within a very small range in relation to one another.

Some solids can vapourize directly into a [[Physics:Gas|gas]]. This is called sublimation. Examples of this are [[Chemistry:Dry ice|dry ice]] becoming [[Physics:Carbon dioxide|carbon dioxide]] [[Physics:Gas|gas]], and [[Earth:Ice|ice]] disappearing without [[Physics:Melting|melting]].

Some of the properties of a solid are [[Physics:Bulk modulus|bulk modulus]],which is a measure of how a solid responds to deformation, [[Physics:Hardness|hardness]], which is a measure of how a solid resists abrasion, and [[Physics:Melting point|melting point]], which is the temparature at which a solid becomes a [[Liquid|liquid]]. 

Solids at their respective [[Physics:Melting point|melting point]] change to [[Liquid|liquid]]s.  

A crystaline solid has atoms or molecules aranged in a regular repeated pattern and may abruptly change phase as the temperature changes.

An [[Physics:Amorphous solid|amorphous solid]] is an apparently solid substance that does not abruptly change its phase as its [[Temperature|temperature]] changes. The atoms or molecules in it are aranged randomly.



==Solid measures== 
Quantities of liquids are measured in units of [[Volume|volume]], such as the [[Cubic metre|cubic metre]] (m³), and [[Mass|mass]], such as the [[Kilogram|kilogram]] (kg).
