Question

Which among the following is NOT an amorphous solid?

Options

• Tar

• Camphor

• Butter

• Rubber

Answer 1

Camphor

Explanation:

• Camphor is a crystalline solid, meaning it has a highly ordered, repeating arrangement of molecules. Crystalline solids have a sharp, definite melting point.
• The other options are all examples of amorphous solids, which lack a long-range, ordered structure and melt over a range of temperatures. Amorphous solids are often referred to as “supercooled liquids” or “pseudo solids”.
