Why does diamond have higher melting point than …

1/10/2010· Silicon carbide has a very high melting point. Suggest why the melting point of diamond is higher than that of silicon carbide. SiC does melt, and diamond melts, but only under pressure. Pwerhaps it is because diamond is all carbon. Please see sites below.

Cohesive tension: intermolecular forces among molecules of a liquid. Vapor pressure The presence of intermolecular forces among gaseous particles, including noble gases, leads to deviations from ideal behavior, and it can lead to condensation at sufficiently low temperatures and/or high pressures.

Why is Silicon dioxide macromolecular? | Yahoo Answers

17/4/2008· Consequently the only intermolecular forces in pure carbon dioxide are London dispersion forces. The electron structure of SiO2 is very different. Unlike CO2, where there is excellent overlap between carbon and oxygen 2px orbitals and between 2py orbitals, there is very poor overlap between the silicon 3px and 3py orbitals and the oxygen 2px and 2py orbitals.

Atomistic processes during nanoindentation of …

Atomistic mechanisms of nanoindentation of a-SiC have been studied by molecular dynamics simulations. The load displacement curve exhibits a series of load drops, reflecting the short-range topological order similar to crystalline 3C–SiC. In contrast to 3C–SiC, the load drops are irregularly spaced and less pronounced. The damage is spatially more extended than in 3C–SiC, and it exhibits

SOLID STATE - GO VIDYALAYA GO - Google Sites

While the intermolecular forces of attraction tend to keep the particles closer; the thermal energy tends to keep the particles apart from each other by making them move faster. When the net resultant of these two opposing forces, i.e. intermolecular forces and thermal energy, makes the particles cling together and forces them to occupy fixed positions, matters exist in solid state.
