intermolecular

Examples of intermolecular in the following topics:

• Surface Tension and Capillary Action

  • It occurs because of intermolecular attractive forces between the liquid and solid surrounding surfaces.
  • With some pairs of materials, such as mercury and glass (see ), the intermolecular forces within the liquid exceed those between the solid and the liquid, so a convex meniscus forms, and capillary action works in reverse.

• Phase Changes and Energy Conservation

  • But the heat added does not change the temperature; that heat energy is instead used to break intermolecular bonds and convert ice into water.
  • At the boiling point, temperature no longer rises with heat added because the energy is once again being used to break intermolecular bonds.

• Evaporation

  • For molecules of a liquid to evaporate, they must be located near the surface, be moving in the proper direction, and have sufficient kinetic energy to overcome liquid-phase intermolecular forces.

• Friction: Static

  • Additionally, intermolecular forces can greatly influence friction when two materials are put into contact.

• Specific Heat for an Ideal Gas at Constant Pressure and Volume

  • This represents the dimensionless heat capacity at constant volume; it is generally a function of temperature due to intermolecular forces.

• Humidity, Evaporation, and Boiling

  • For the molecules to evaporate, they must be located near the surface, be moving in the proper direction, and have sufficient kinetic energy to overcome liquid-phase intermolecular forces.
