Assertion: Amorphous solids have definite geometrical shape.

Reason: Amorphous solids do not have any type of symmetry.

Assertion is wrong statement, but reason is correct statement.

The correct answer is option 4. Assertion is wrong statement, but reason is correct statement.

Let us delve deeper into the concepts of amorphous solids and the provided statements:

Assertion: Amorphous solids have definite geometrical shape.

Amorphous Solids are solids where the constituent particles (atoms, molecules, or ions) are not arranged in a regular, repeating pattern over long distances. Examples include glass, plastics, and gels. Unlike crystalline solids, which have a well-defined, repeating lattice structure, amorphous solids have a disordered arrangement of particles. Because amorphous solids lack this regular arrangement, they do not have a definite geometrical shape. Instead, they can have varied shapes and do not exhibit the distinct flat faces and sharp angles seen in crystalline solids.

Reason: Amorphous solids do not have any type of symmetry.

Symmetry refers to the orderly and repetitive arrangement of particles in a material. In crystalline solids, this symmetry is a result of their regular lattice structures, leading to properties like distinct melting points and well-defined shapes. Amorphous solids do not have such an orderly arrangement. Their internal structure is more like that of a liquid, albeit frozen in place. This lack of long-range order means that they do not possess the types of symmetry that are characteristic of crystals.

Assertion: The assertion is incorrect. Amorphous solids do not have a definite geometrical shape because their internal structure is disordered. They do not form the regular, repeating patterns necessary to maintain a definite shape.

Reason: The reason is correct. Amorphous solids lack symmetry because their particles are not arranged in a regular, repeating pattern. This is a key characteristic of amorphous solids and explains why they do not have a definite geometrical shape.

The assertion that "Amorphous solids have definite geometrical shape" is wrong because amorphous solids, by definition, lack the regular structure needed to have a definite shape.

The reason that "Amorphous solids do not have any type of symmetry" is correct because the disordered arrangement of particles in amorphous solids means they lack the symmetrical properties found in crystalline solids.

Therefore, the correct evaluation of the statements is 4. Assertion is wrong statement, but reason is correct statement.
