The greater the intermolecular attraction, the higher the melting point and boiling point. Melting and boiling are both processes which have to overcome intermolecular attraction.


The stronger the intermolecular forces, the higher the melting point and boiling point. The weaker the intermolecular forces, the lower the melting and boiling points are.


An intermolecular force has both a boiling point and melting point


Melting and boiling points are determined by the strength of the intermolecular forces present in the compound. The stronger the intermolecular forces, the higher the melting and boiling points. There are four types of intermolecular forces, from lowest strength to highest: London dispersion forces, dipole-dipole, hydrogen bonding, and ion-dipole. Ionic compounds will have ion-dipole intermolecular forces. Because this is the strongest intermolecular force, ionic compounds will also have the highest melting and boiling points.


The greater the intermolecular forces in a liquid, the higher is its boiling point.


Low intermolecular forces, low boiling point.


The physical properties of melting point, boiling point, vapor pressure, evaporation, viscosity, surface tension, and solubility are related to the strength of attractive forces between molecules.


as the intermolecular forces increses the boiling point is increses


The structure of a compound will dictate what intermolecular forces hold the molecules together. The stronger these forces, the higher will be the boiling point.


Dipoles are a form of intermolecular force which holds molecules together. The greater the intermolecular force, usually the greater the boiling point, for example.


Boiling can only occur when the kinetic energy of heat overcomes the intermolecular forces holding a liquid together, so the greater the intermolecular forces, the higher the boiling point.


The stronger the intermolecular forces, the higher the boiling point, because more kinetic energy is needed to break these intermolecular forces apart.


The melting and boiling point of a substance is largely determine by the intermolecular forces which hold its molecules together. These may included Van der Waals forces (dispersion forces), dipole-dipole interactions, as well as hydrogen bonding. The stronger these forces act between molecules, the high the melting point and boiling point of the substance.


A discrete atom or molecule is one with very weak intermolecular forces, causing them to have low melting and boiling points.


It is because the intermolecular forces(the attractive forces between the molecules of a substance) differ from one substance to another. The chemical with the stronger intermolecular forces will have higher melting and boiling points, and vice versa. This is because more energy is required to separate the molecules to melt or boil the substance, if the forces are strong. The factors that determine the size of these forces are :the type of bonding in the molcules, andthe mass of the molecules.


The stronger the forces the stronger the attraction between the molecules in the substance. This will tend to increase the temperature of phase changes, melting and boiling points.


The correct answers are: Capillary attraction; Melting point; and Heat of vaporization. Stronger intermolecular forces increase capillary attraction, melting point, and the heat of vaporization. They have no bearing on conductivity and hardness.A.HardnessB.ConductivityC.Capillary attractionD.Melting pointE.Heat of vaporization


ionic compounds have high melting points because the have strong intermolecular forces Molecular compounds boiling point is lower however because they have less strong intermolecular forces. the strength of the intermolecular forces vary with the strength of the electro negativity of an atom. for instance H2O has a higher boiling point than H2S because Oxygen has a higher electro negativity. The strength of the intermolecular forces between non-polar molecules is even weaker than that between polar molecules.

The forces between a molecule and its neighbours are much weaker. It is these intermolecular forces, not the covalent bonds, that must be overcome when the substances melts or boils


The intermolecular forces within a solid are stronger than the similar forces in a liquid or a gas; as a consequence solids are harder, denser, having generally high melting and boiling points.


Capillary attraction, Melting point, Heat of vaporization Sublimation temperature, Surface tension, Vapor pressure, Heat of fusion Boiling point, Viscosity, Density, Heat of sublimation Apex: Boiling point, viscosity, heat of sublimation, density.


Polar molecules have relatively weak intermolecular forces. Intermolecular forces and boiling point have a direct relationship, so due to the fact that polar molecules have weak forces, their boiling points will be lower.


Viscosity is the thickness of the compound. The thicker the compound the higher the intermolecular forces. The higher the intermolecular forces the higher the boiling point is.


The melting point and boiling point of a substance come under the category of phase changes. And the temperature at which these phase changes occur are related to the intermolecular forces holding the molecules of the substance together.
