The only reason liquids dont vaporise instantly is because of external atmospheric pressure and that the molecules arent energetic enough to be in the gas state. This however doesnt stop a large number of molecules from escaping the surface as a vapour, because considering entropy reasons, the liquid 'wants' to vaporise because this will make it more disorderly as a gas. according to modern science the universe and everything in it tends to move to a state of greater disorder, its just one of those laws. differences in volatility depend on intermolecular forces, those with weaker forces will have a greater volatility than those with stronger forces.

Because their boiling point is around average room temperature. Generally this occurs in liquids which have short-medium length hydrocarbon chains like gasoline, because there are such weak intermolecular van der waal's forces holding the molecules together.
the carbon and hydrogens electron affinity with oxygen they love to share each others electrons so as the final 8 electron shell configuration is achieved a good tool for you would be the periodic table of the elements paying particular attention to electron configurations once that is understood chemistry becomes easy to study making chemical equasions childs play

Its vapor pressure is greater than the atmospheric pressure. If the gasoline was placed in a pressure vessel and the pressure increased, at some point the gasoline would not vapoize.
