WebFeb 21, 2024 · Explanation: The more electrons a molecule has, the greater the intermolecular attractions. Also, a larger size increases the London dispersion forces. The increased attraction of the molecules to each other means that more energy is needed to separate them from each other. Hence, the boiling point increases. Answer link Webmelting and boiling points increase with: increasing atomic/molecular size why do larger atoms have a higher melting and boiling point? In a larger atom, the valence electrons are, on average, farther from the nuclei than in a smaller atom. Thus, they are less tightly held and can more easily form the temporary dipoles that produce the attraction. biobutanol production technical report

WebAs metals are giant lattice structures, the number of electrostatic forces to be broken is extremely large, and so metals have high melting and boiling points. This means that the melting... WebFor this reason boiling points need to be measured at a specific atmospheric pressure. This is 1 atmosphere pressure, 1 x 10 5 Nm-2. The boiling point is a measure of the strength of the interparticular forces within the body of a liquid. It is a more convenient comparison for many volatile substances, as their melting points are often too low.
