The strength of intermolecular forces in liquids, solids, and gases depend directly on?
Correct answer: C. Distance b/w molecules
- A. Speed of atoms
- B. Motion of particles
- C. Distance b/w molecules
- D. All of these options are correct
Explanation
OPTION A: The intermolecular forces are dependent on the distribution of electrons and the shape of the molecules, not on the speed of atoms themselves.OPTION B: The strength of intermolecular forces in liquids, solids, and gases does not depend directly on the motion of particles because intermolecular forces are due to the attractive forces between molecules and are not directly influenced by the kinetic energy of particles.OPTION C: The strength of intermolecular forces is affected by the distance between the molecules. As the distance between the molecules is increased, the intermolecular forces rapidly decrease in strength.OPTION D: It is not possible.

About Properties of Liquids
Liquid behavior depends on intermolecular forces, which produce surface tension, viscosity, capillary action and a definite volume without a fixed shape. The topic also covers vapor pressure, evaporation, boiling point and the effect of temperature and external pressure, while distinguishing evaporation at the surface from boiling throughout the liquid.
