	Alcohols have several different uses. [[Methanol]] and [[ethanol]] can be used as [[bioethanol\|alternative fuels]] in vehicles due to the fact that they burn very cleanly. Some alcohols, specifically ethanol, are used as solvents in products such as perfumes, cosmetics, and plant extracts to keep them "fresh" and act as an alternative solvent for compounds that are insoluble in water. They can also be used as cleaning agents for items like paint brushes.<ref>At-Bristol Science Center. (2014). ''Alcohol Uses'' [Online].

==Properties==
Alcohols are generally colourless and [[liquid]] at room [[temperature]]. Due to the polarity of their bonds, they are also highly soluble in water. However this solubility tends to decrease as the size and weight of the molecule increase. As well, as their molecular weight increases, their boiling points, densities, and viscosities increase.<ref>Jim Clark. (2003). ''An Introduction to Alcohols'' [Online]. Available: http://www.chemguide.co.uk/organicprops/alcohols/background.html [March 2, 2015]</ref> Many smaller alcohols like ethanol considered [[volatile]]<ref> ''Ethanol'' [Online]. Available: http://www.npi.gov.au/resource/ethanol-ethyl-alcohol [March 16th, 2015]</ref> which helps them [[combustion|burn]].
