Question

What are 2 types of a solid?

Answer 1

Hint: Substances in which the atoms or molecules are very close to each other and having very high intermolecular forces are known as solids. So, there are two types of solids, i.e., one in which the arrangement of the atoms or molecules are definite and the other in which the arrangement of the atoms or molecules are indefinite.

Complete answer:
We know that according to the arrangement of the atoms or molecules in the substance, there are three types of substance, i.e., solids, liquids, and gases. Substances in which the atoms or molecules are very close to each other and having very high intermolecular forces are known as solids.
According to the arrangement of the atoms or molecules, solids are further divided into two types, i.e., crystalline solid and amorphous solid. The solid in which there is a definite arrangement of atoms or molecules, those are known as crystalline solids, and the solids in which there is no definite arrangement of atoms or molecules, those are known as amorphous solids.
Some properties of crystalline solids are they have a sharp melting point, they have high heat of fusion, they are anisotropic, and they have clean cleavage. Some properties of amorphous solids are they do not have a sharp melting point, they have a low heat of fusion, they are isotropic, and they do not have clean cleavage.

Note:
Some examples of crystalline solids are diamond, mica, sugar, quartz, etc and some examples of amorphous solids are plastic, glass, rubber, polymers, gel, etc. Another name of amorphous solid is a pseudo solid or supercooled liquid.
