Answer to Question 1

ANS: D
Amorphous solids are sometimes called supercooled liquids. Elements and compounds alone can combine to form either crystalline or amorphous solids.

Answer to Question 2

ANS: D
Glass and margarine are always considered amorphous solids. Plastic usually shows flexibility, which implies that it has amorphous features, so it should be considered amorphous. Iron, however, has well-organized atoms in a crystalline arrangement.
