Pseudo solids or Amorphous solids- Substances which look like solids but actually are not solids are called pseudo solids. These do not have definite geometrical structure because the constiutent particles are not arranged in an orderly manner but in a random manner. These are actually regarded as super cooled liquids. These lose their shape on standing and flow under their own weight, eg glass, pitch, rubber, plastics, starch and proteins.
