→Limitations of the Particle Model
| style="height:20px; width:100px; text-align:left;" |[[Particle]]s are [[sphere]]s.
| style="height:20px; width:200px; text-align:left;" |[[Particle]]s are often [[molecule]]s whose shape is not a [[sphere]], some of which are long chains of [[atom]]s.
| style="height:20px; width:300px; text-align:left;" |: Differently shaped [[particle]]s fit together in different ways which can change the [[property|properties]] of [[solid]]s and [liquid]]s such as the [[strength]] or [[viscosity]].
|-
| style="height:20px; width:100px; text-align:left;" |There are no [[force]]s between [[particle]]s.
| style="height:20px; width:200px; text-align:left;" |[[Intermolecular Force]]s exist between [[molecule]]s.
| style="height:20px; width:300px; text-align:left;" |
: The strength of the [[Intermolecular Force|intermolecular forces]] affects whether a substance is [[solid]], [[liquid]] or [[gas]] at different [[temperature]]s. The stronger the [[Intermolecular Force|intermolecular forces]] the higher the [[temperature]] of its [[Melting Point|melting point]] and [[Boiling Point|boiling point]].: The direction of the [[Intermolecular Force|intermolecular forces]] affects the way the [[particle]]s are arranged in a [[solid]].
|-
| style="height:20px; width:100px; text-align:left;" |The size of all [[particle]]s in a [[substance]] is the same.
| style="height:20px; width:200px; text-align:left;" |A [[substance]] can be made of more than one different [[particle]] which have different sizes.
| style="height:20px; width:300px; text-align:left;" |
: The different size [[particle]]s causes them to fit together in different arrangements in a [[solid]].
