Question

Identify the type of physical properties you would need to consider in comparing the strength of intermolecular forces in solids and liquids.

Answer 1

Among them there are both low-melting (sulfur, selenium, phosphorus) and refractory substances (graphite, diamond, silicon, boron). The melting points of these substances do not depend on their relative atomic mass: the relative atomic mass of iodine is 127, and boron is only 11, but the melting point of boron is much higher.
