Smaller molecules have lower melting points
Did you know?
WebbSimple molecules have low melting or boiling points because there are weak intermolecular forces of attraction between molecules. , Weak forces need little energy … The melting temperature of a bulk material is not dependent on its size. However, as the dimensions of a material decrease towards the atomic scale, the melting temperature scales with the material dimensions. The decrease in melting temperature can be on the order of tens to hundreds of degrees for metals with nanometer dimensions. Melting-point depression is most evident in nanowires, nanotubes and nanoparticles, which all mel…
