==Key Stage 3==
===Meaning===
The '''particle model''' is a scientific theory that all matter is made of particles, and that those particles behave differently in solids, liquids and gases.
===About The Particle Model===
: The '''particle model''' [[explain]]s the [[properties|properties]] of [[solid]]s, [[liquid]]s and [[gas]]es.
: The '''particle model''' can [[explain]] [[State Changes|changes of state]].
: [[Scientific Evidence|Evidence]] of the '''particle model''' can be shown by pouring 50[[ml]] of [[pure]] [[water]] and 50[[ml]] of [[pure]] [[ethanol]] into a [[Measuring Cylinder|measuring cylinder]]. The [[solution]] is only 97[[ml]] because [[ethanol]] [[molecule]]s are bigger than [[water]] [[molecule]]s so the [[water]] [[molecule]]s fit between the [[ethanol]] [[molecule]]s like pouring 50[[ml]] of sand and 50[[ml]] of marbles into the same container. It will not make 100[[ml]].
