On Titan, the largest moon of Saturn, methane (CH4\text{CH}_4CH4) exists in liquid form in lakes due to the extremely low surface temperatures. On Earth, at standard atmospheric pressure, methane boils at −161.5 ∘C-161.5\ ^\circ\text{C}−161.5 ∘C.
Explain, in terms of intermolecular forces, why methane has a very low boiling point.
