    Amorphous solids are not true solids. Why and what are they called then?

    Answer:

                    Like liquids, amorphous solids have disordered arrangement of atoms or molecules. The molecules of a liquid are free to move but the molecules of an amorphous solid are almost fixed at their positions i.e., amorphous solids are rigid due to their high viscosity. That is why, we say amorphous solids are super-cooled liquids of high viscosity.
