State your reasons for the order you use (identify the forces and explain how they affect the boiling point). Explain the statements below on. Therefore according to this statement gases will have the higher kinetic energy in comparison to intermolecular forces, solids will gave greater intermolecular forces in comparison to kinetic energy, and liquids are in the middle with kinetic energy less than intermolecular forces but not as significant of a difference in comparison to solids. far,. Z. Sandler 1991 A Solomon Press book. Going from gas to liquid to solid, molecular velocities and particle separations diminish progressively as structural order increases. As a result, substances with higher molecular weights have higher London dispersion forces and consequently tend to have higher melting points, boiling points, and enthalpies of vaporization. 0000000016 00000 n

Combine various metal and nonmetal atoms to observe how the electronegativity difference determines the polarity of chemical bonds. The forces that hold molecules together in the liquid and solid states are called intermolecular forces. The tendency of a substance to be found in one state or the other under certain conditions is largely a result of the forces of attraction that exist between the particles comprising it. They are different in that liquids have no fixed shape, and solids are rigid. They must affect all states of matter, this is because in order to change states of matter, then intermolecular forces are involved. Explanation: First few have hydrogen bonding with more hydrogen bonding = higher boiling point due to higher IMFs, last two are ordered that way because the one with higher molecular weight will have a higher boiling point due to higher IMFS.
