What is a polymer?

Choose 1 answer

A polymer is a long chain molecule made by the addition of many small molecules called monomers.

A polymer is a substance that is made of short chain molecules that consists of a unit called gnomes. Polymers are more commonly known as plastics.

A polymer is a substance that is made of long chain molecules that consists of a repeating unit called arcs. Polymers are more commonly known as plastics.

A polymer is a substance that is made of rubber. Polymers are more commonly known as plastics.
