===Meaning===
'''State of matter''' means whether a [[material]] is [[solid]], [[liquid]] or [[gas]].
===About States of Matter===
: [[Material|Materials]] can be [[solid]], [[liquid ]] or [[gas]].
: The '''state of matter''' can be changed by heating or cooling the material.
: Heating can turn a [[solid ]] into a [[liquid and ]]. This is called [[melting]].: Heating can turn a [[liquid ]] to a [[gas]]. This is called [[evaporating]].: Cooling can turn a [[gas ]] into a [[liquid and ]]. This is called [[condensing]].: Cooling can turn a [[liquid ]] into [[solid]]. This is called [[freezing]]. ====Solid====

===About States of Matter===
: [[Material|Materials]] can be [[solid]], [[liquid]] or [[gas]].
: The '''state of matter''' can be changed by heating or cooling the material.
: Heating can turn a [[solid]] into a [[liquid]] by [[melting]] or it can turn a [[solid]] straight into a [[gas]] by [[subliming]].
: Heating can turn a [[liquid]] to a [[gas]]. This is called [[evaporating]].
: Cooling can turn a [[gas]] into a [[liquid]] by [[condensing]] or it can turn a [[gas]] into a [[solid]] by [[depositing]].

'''State of matter''' means whether a [[material]] is [[solid]], [[liquid]] or [[gas]].
===About States of Matter===
: [[Material|Materials]] can be [[solid]], [[liquid]] or [[gas]].
: The '''state of matter''' can be altered by changing the [[temperature]] of the [[material]] or changing the [[pressure]] on the [[material]].
: The [[property|properties]] of [[solid]]s, [[liquid]]s and [[gas]]es can be explained by the way the [[particle]]s inside those [[substance]]s behave.

Examples ====Why isn't everything a gas?====: When [[particle]]s are near each other, they tend to stick together. This is due to [[force]]s acting between [[adjacent]] [[particle]]s. When two [[particle]]s are near one another they are [[attracted]] together. This causes those [[particle]]s to come together. Without this [[force]] of [[attraction]] between particles they would not stick together and there would be no [[solid]] or [[liquid]] '''states'''.: What determines if a [[substance]] is a [[solid]], [[liquid]] or [[gas ]] at [[MaterialRoom Temperature|materialsroom temperature]] is how big that [[force]] of [[attraction]]is. ====Why Solids and Liquids exist====:Different [[substance]]s have a different [[force]] of [[attraction]] between the [[adjacent]] [[particle]]s.*Air : Silicon dioxide (A mixture sand and glass) is [[solid]] at [[Room Temperature|room temperature]] because there is a strong [[force]] of gases[[attraction]] between [[adjacent]] [[molecule]]s.: [[Water]] is a [[liquid]] at [[Room Temperature|room temperature]] because the [[force]] of [[attraction]] is not great enough to hold the [[molecule]]s in position. However, mostly nitrogen and oxygen)it is great enough to keep them together. : [[Oxygen]] is a gas at [[Room Temperature|room temperature]] because there is a very weak [[force]] of [[attraction]] between [[adjacent]] [[molecule]]s. ===References=======AQA==== :[https://www.amazon.co.uk/gp/product/1782945970/ref=as_li_tl?ie=UTF8&camp=1634&creative=6738&creativeASIN=1782945970&linkCode=as2&tag=nrjc-21&linkId=a120d24dcc7cc7a58192069a3aafc1d2 ''States of matter, pages 106, 107, 110-113, GCSE Physics;
