Intermolecular Forces Affect Many Physical Properties

Intermolecular Forces Affect Many Physical Properties. The strength of the attractions between particles can greatly affect the properties of a substance or solution.. Viscosity. Resistance of a liquid to flow is called viscosity.It is related to the ease with which molecules can move past each other.Viscosity increases with stronger intermolecular forces and decreases with higher temperature..

    3. Viscosity Resistance of a liquid to flow is called viscosity. It is related to the ease with which molecules can move past each other. Viscosity increases with stronger intermolecular forces and decreases with higher temperature.

    4. Phase Changes

    5. Energy Changes Associated with Changes of State Heat of Fusion: Energy required to change a solid at its melting point to a liquid.

    6. Energy Changes Associated with Changes of State Heat of Vaporization: Energy required to change a liquid at its boiling point to a gas.

    7. Energy Changes Associated with Changes of State The heat added to the system at the melting and boiling points goes into pulling the molecules farther apart from each other. The temperature of the substance does not rise during the phase change.
