SUMMARY
The boiling point of a substance is directly influenced by its molecular weight due to the relationship between molecular size and dispersion forces, a type of van der Waals force. Dispersion forces, or induced dipole-induced dipole interactions, increase with the polarizability of molecules, which is determined by the number of electrons and molecular size. As molecular weight increases, so does the polarizability, leading to stronger intermolecular interactions and higher boiling points.
