If you are studying abroad for your post-16 education you will require a general student visa. 1  In the UK this is called a Tier 4 (General Student) visa. 2  In the US this is called a F-1 visa. 3  In Australia your visa type will depend on your country of citizenship and your chosen subject.
Isopropyl alcohol dissolves a wide range of non-polar compounds. It also evaporates quickly, leaves nearly zero oil traces, compared to ethanol, and is relatively non-toxic, compared to alternative solvents. Thus, it is used widely as a solvent and as a cleaning fluid, especially for dissolving oils.
That is why we want to get rid of water in fuel tanks. To do this, isopropyl alcohol is added to serve as a 'gas dryer' in fuel. Isopropyl alcohol makes water soluble in gasoline, so once it is soluble, it eliminates the risk of water freezing and blocking fuel lines.
