The intermolecular forces are very weak in _ ?
Correct answer: C. Gases
- A. Solids
- B. Liquids
- C. Gases
- D. All of these
Explanation
Intermolecular forces are the forces of attraction between molecules. These forces play a significant role in determining the physical properties of substances, such as their boiling points, melting points, and states of matter.The intermolecular forces are very weak in gases. In gases, the particles (atoms or molecules) are typically at a greater distance from each other compared to solids and liquids, resulting in weak intermolecular forces. Gases have the lowest density and the most kinetic energy among the three states of matter (solid, liquid, and gas), which allows them to move freely and independently of each other. The intermolecular forces in solids and liquids are stronger due to the closer proximity of particles.

About Kinetic Molecular Theory
Kinetic molecular theory explains gases as rapidly moving particles separated by large distances, with negligible volume and negligible intermolecular attraction in the ideal model. It relates temperature to average kinetic energy and explains gas pressure, Boyle's and Charles's laws, diffusion, effusion and the conditions under which real gases deviate from ideal behavior.
