Question

Select the true statement(s) abut Polymers: Group of answer choices Thermoplastics have low melting temperature because of the week van der Waals bonds between their Long Chain Molecules Thermoplastics have low strength because of the week van der Waals bonds between their Long Chain Molecules Polymers have low densities because of the week van der Waals bonds between their Long Chain Molecules Polymer chains once synthesized they will remain stable in the environment because of the strong covalent bonds in the Long Chain Molecules

Answer 1

Answer:

Thermoplastics have low melting temperature because of the week van der Waals bonds between their Long Chain Molecules

Polymer chains once synthesized they will remain stable in the environment because of the strong covalent bonds in the Long Chain Molecules

Explanation:

Thermoplastics are polymers that are easily melted and changed to another shape as many times as possible. They become molten when they are heated and solidify when cooled. Examples of thermoplastics include; polyethylene, polypropylene, polyvinyl chloride, polystyrene, polyamides, polyesters, and polyurethanes.

Polymers are organic materials that consists of a long chain of atoms held together by strong covalent bonds. Polymers constitute an important environmental concern because most polymers are non biodegradable and remain in the environment almost indefinitely.
