The melting and boiling point of liquids depends upon the _.
Correct answer: B. Intermolecular forces between the molecules
- A. Motion of liquid molecules
- B. Intermolecular forces between the molecules
- C. Kinetic energy of the molecules
- D. Mass of the molecules
Explanation
When the kinetic energy of molecules becomes maximum, a stage comes when the temperature is no longer increased and this heat energy is used to break intermolecular forces /bonds and convert liquid into liquid or gas.

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.
