Question

state proporties of amorphous substances.​

Answer 1

Answer:

• They do not have a sharp and definite melting point. Therefore, they melt over a large range of temperature and are mostly insoluble in water.

eg : glass, chalk, coke, rubber, borates, magnesium carbonate, etc.

• An interesting class of amorphous solids are plastics such as bakelite, polyethylene, polystyrene and nylon. They consist of molecules that are cross-linked together to produce a giant random network.
• Organic substances such as pitch, wax, higher alkanes, proteins, etc. are also amorphous.

Answer 2

Answer:

Amorphous solids lack a characteristic geometry, have identical properties along all axes, have wide ranges over which they melt, and break to form curved or irregular shapes. It is important to note that these terms mark two extremes on a continuum. Most amorphous solids have some short-range order.
