EVERYDAY SCIENCE

Detailed explanation-1: -They are firm, hold a definite and fixed shape, are rigid and incompressible. They generally have geometric shapes and flat faces. And examples include diamonds, metals, salts etc.

Detailed explanation-2: -Solids have definite shapes and definite volumes and are not compressible to any extent. There are two main categories of solids-crystalline solids and amorphous solids. Crystalline solids are those in which the atoms, ions, or molecules that make up the solid exist in a regular, well-defined arrangement.

Detailed explanation-3: -Crystalline solids consist of particles that are arranged in a three-dimensional manner. The intermolecular forces between them are equal. They are anisotropic and have a well-defined melting point as well. They are referred to as the true solids.

Detailed explanation-4: -Crystalline solids are true solids, have a regular arrangement of particles (long range order) whereas amorphous solids have an irregular arrangement of particles ( short range order). Due to this, crystalline solids are true solids and amorphous solids are pseudo solids.

Detailed explanation-5: -Crystalline Solids – Particles are arranged in a repeating pattern. They have a regular and ordered arrangement resulting in a definite shape.
