Assertion (A): Three states of matter are the result of balance between intermolecular forces and thermal energy of the molecules.
Reason (R): Intermolecular forces tend to keep the molecules together but thermal energy of molecules tends to keep them apart.
Explanation:
The given assertion and reason are both true, and the reason is the correct explanation of the assertion.
Intermolecular Forces:
Intermolecular forces are the forces of attraction between molecules. These forces determine the physical properties of matter, such as boiling point, melting point, and density. The strength of intermolecular forces depends on the type of molecules and the distance between them.
Thermal Energy:
Thermal energy is the energy associated with the random motion of particles in a substance. It is directly related to temperature. As the temperature of a substance increases, the thermal energy of its molecules also increases. Thermal energy causes the molecules to move faster and have more kinetic energy.
States of Matter:
There are three states of matter: solid, liquid, and gas. These states arise due to the balance between intermolecular forces and thermal energy.
Solid State:
In solids, intermolecular forces are strong, and thermal energy is relatively low. The molecules are closely packed and arranged in a regular pattern. The intermolecular forces hold the molecules tightly together, preventing them from moving freely. As a result, solids have a definite shape and volume.
Liquid State:
In liquids, intermolecular forces are weaker than in solids, and thermal energy is higher. The molecules are still close together but can move past each other. The intermolecular forces are not strong enough to keep the molecules in a fixed position. Therefore, liquids can flow and take the shape of their container, but they still have a definite volume.
Gaseous State:
In gases, intermolecular forces are very weak, and thermal energy is high. The molecules are far apart and move freely in all directions. The thermal energy overcomes the intermolecular forces, allowing the molecules to spread out and occupy the entire volume of the container. Gases have neither a definite shape nor a definite volume.
Conclusion:
The balance between intermolecular forces and thermal energy determines the state of matter. Intermolecular forces tend to keep the molecules together, while thermal energy tends to keep them apart. Depending on the strength of intermolecular forces and the amount of thermal energy, matter can exist in solid, liquid, or gaseous states.
Reason (R): Intermolecular forces tend to keep the molecules together but thermal energy of molecules tends to keep them apart.
