Consider the following statements with reference to the intermolecular...
Intermolecular forces tend to keep the molecules together but the thermal energy of the molecules tends to keep them apart. Three states of matter are the result of a balance between intermolecular forces and the thermal energy of the molecules. Hence the correct option is (c)
When molecular interactions are very weak, molecules do not cling together to make liquid or solid unless thermal energy is reduced by lowering the temperature.
Gases do not liquify on compression-only, although molecules come very close to each other and intermolecular forces operate to the maximum. However, when the thermal energy of molecules is reduced by lowering the temperature; the gases can be very easily liquified.

Consider the following statements with reference to the intermolecular...
Explanation:
Intermolecular forces tend to keep the molecules of different states of matter together: This statement is correct. Intermolecular forces are attractive forces between molecules that hold them together. These forces are responsible for keeping the molecules in a solid or liquid state close to each other. For example, in a solid, the intermolecular forces are strong enough to maintain a rigid structure, while in a liquid, they allow the molecules to move past each other but still stay close together.
Thermal energy of the molecules tends to keep the molecules of different states of matter apart: This statement is also correct. The thermal energy of molecules increases with temperature, causing them to move faster and overcome the intermolecular forces holding them together. This results in the molecules being further apart from each other in a gaseous state compared to a liquid or solid state. The higher the temperature, the more kinetic energy the molecules have, leading to a greater separation between them.
Therefore, both statements are correct as they highlight the opposing effects of intermolecular forces and thermal energy on the arrangement of molecules in different states of matter.
