Changes

: For most [[substance]]s the [[solid]] [[State of Matter|state]] is more [[Density|dense]] than the [[liquid]] [[State of Matter|state]]. However, this is not the case for [[water]].

: [[Water]] is known as a [[Polar Molecule|polar molecule]] which means one part is slightly [[Positive Charge|positively charged]] and the other is slightly [[Negative Charge|negatively charged]]. Since there is strong [[force]] of [[attraction]] pulling the [[electron]]s towards to [[Oxygen]] [[atom]] in [[water]] then the [[Oxygen]] becomes slightly [[Negative Charge|negative]] and the [[Hydrogen]] [[atom]]s become slightly [[Positive Charge|positively charged]]. This causes the [[molecule]]s to line up with a [[Hydrogen]] of one [[molecule]] touching the [[Oxygen]] in another [[molecule]].
