1.1 Define the term 'amorphous'. Give a few examples of amorphous solids.
Amorphous solids have the constituent particles arranged only in short-range order and consequently, they behave like supercooled liquids. So do not have sharp melting points. Also, they are isotropic in nature i.e., their physical properties are the same in all directions.
E.g. quartz glass, polymers, gels etc.
