What sort of analogy is good to use for remembering how the length of hydrocarbon chains affect the properties such as melting point and volatility?

Many good questions generate some degree of opinion based on expert experience, but answers to this question will tend to be almost entirely based on opinions, rather than facts, references, or specific expertise. If this question can be reworded to fit the rules in the help center, please edit the question.
Imagine two bins of cables, one has 20 1m cables the other has 20 10m cables. Imagine each cable as a chain. The 10m cables will be harder to untangle and therefore harder for the molecules to break away from each other, giving the longer cables/hydrocarbons a higher melting point and viscosity. Because of this, the volatility is lowered in longer chains.
This will help you remember the properties.
