Alkane/Talk

I think there should be a mention to the way the different alkanes are related to common fuels, and their physical properties. Methane is a gas at normal condition, and very difficult to liquify, (methane + ethane = natural gas? not sure), butane and propane are also gases, but they can be liquified rather easily, and so they are sold in cilinders, in liquid form. Those cilinders are easily recharged. pentane and hexane, i'm not sure, but heptane and octane are liquid in normal conditions, are main constituents of gasoline. Somewhere in the tens of carbons, the alkanes are solid in normal conditions (paraffine)....etc..
