The differences in their room-temperature phases occur because of their differences in molecular weight which makes them more polarized leading to an increase in intermolecular forces. Three obvious consequences of Equations \(\ref{Col}\) and \(\ref{Force}\) are: To complicate matters, molecules and atoms have a distribution \(\rho(\vec{r})\) that result from the 3D distribution of charges (both nuclei and especially electrons). Some covalent compounds are polar, and. Earth, moon, and sun section summary gravity and motion. Web inter molecular forces are the attractions between molecules,. In truth, there are forces of attraction between the particles, but in a gas the kinetic energy is so high that these cannot effectively bring the particles together. Forces of Attractions- Supplemental Worksheet 1. Osmotic pressure problem where i=2 due to the NaCl dissolving into solution. Now we will study about different aspects of solid state.
