When a solid is deformed, all the atoms or molecules are displaced from their equilibrium positions causing a change in interatomic (or intermolecular) distances. This is because solids are composed of a closely packed arrangement of atoms or molecules that are held together by interatomic or intermolecular forces.
Explanation:
1. Deformation of Solids
- Deformation refers to the change in shape or size of a solid when a force is applied to it.
- Solids can be deformed under the influence of external forces, such as compression, tension, bending, or shearing forces.
2. Equilibrium Position
- The equilibrium position is the stable position of atoms or molecules in a solid.
- At equilibrium, the interatomic or intermolecular forces are balanced, resulting in a stable arrangement of particles.
3. Displacement of Atoms or Molecules
- When a solid is deformed, the applied external force causes a displacement of all the atoms or molecules from their equilibrium positions.
- This displacement occurs in all directions and is responsible for the change in shape or size of the solid.
4. Change in Interatomic or Intermolecular Distances
- As the atoms or molecules are displaced from their equilibrium positions, the interatomic or intermolecular distances change.
- The displacement of atoms or molecules leads to a stretching or compression of the interatomic or intermolecular bonds.
- The change in interatomic or intermolecular distances affects the overall structure and properties of the solid.
5. Importance of Option D
- Option D states that all the atoms or molecules are displaced from their equilibrium positions causing a change in interatomic (or intermolecular) distances.
- This option is correct because the deformation of a solid involves the displacement of all its constituent particles, leading to a change in their relative positions and distances.
- The displacement of atoms or molecules from their equilibrium positions is responsible for the observed changes in the shape, size, and mechanical behavior of the solid.
In conclusion, when a solid is deformed, all the atoms or molecules are displaced from their equilibrium positions, causing a change in interatomic (or intermolecular) distances. This displacement occurs in all directions and is responsible for the change in shape or size of the solid.
