Liquids have no definite shape; it is because:
Correct answer: A. The molecules of liquid are in constant motion by sliding over each other
- A. The molecules of liquid are in constant motion by sliding over each other
- B. The intermolecular forces of liquids are weaker than gases
- C. The liquid molecules have kinetic energy less than solids
- D. All statements are correct
Explanation
In liquids, the molecules are in constant motion, which allows them to flow and adapt to the shape of their container.

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.
