====Why isn't everything a gas?====: Whether 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 [[Room Temperature|room temperature]] is determined by the 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 in that .: Silicon dioxide (sand and glass) is [[solid]] at [[Room Temperature|room temperature]] because there is a strong [[force]] of [[attraction]] between [[adjacent]] [[substancemolecule]]s. The stronger : [[Water]] is a [[liquid]] at [[room temperature]] because the [[force]] of [[attraction]] is not great enough to hold the higher the [[Melting Point|melting pointmolecule]]s in position. However, it is great enough to keep them together. : [[Oxygen]] is a gas at [[room temperature]] because there is a very weak [[force]] of the [[substanceattraction]] between [[adjacent]] [[molecules]].
