Intermolecular forces are the forces between molecules that hold the substances together in the solid and liquid phases. Because silicon carbide is made from Group 4A elements, and because it is extremely hard, one would expect SiC to form a covalent 31.
Essay on The Iron-Carbon Diagram - 7780 Words
The Iron–Iron Carbide (Fe–Fe3C) Phase Diagram In their simplest form, steels are alloys of Iron (Fe) and Carbon (C). The Fe-C phase diagram is a fairly complex one, but we will only consider the steel part of the diagram, up to around 7% Carbon.

With functional groups, gas adsorption caused by electrostatic force results in relatively small resistance changes due to the weak intermolecular force. Gas absorption may also be due to the substitution of surface functional groups by gas molecules, which leads to the carrier transfer between adsorbent and adsorbate gas, and significant changes in the resistance of materials ( Geistlinger

High Density Polyethylene - Structure, Properties, and Uses
The structure of HDPE is linear and it contains very little branching, resulting in stronger intermolecular forces. The tensile strength of high-density polyethylene is very high – it can withstand heavier loads than most of the other types of polyethylene.
Rubber and its Types | Chemistry Learning
Rubber is a natural polymer of Isoprene (2-Methyl -1, 3 – Butadiene). It is a linear, 1, 4 – addition polymer of Isoprene. Natural rubber has elastic properties and it undergoes long range reversible extension even if relatively small force is applied to it. Therefore, it is
