Question
- A. They can be remolded multiple times.
- B. They are always rigid.
- C. They are made from only one type of monomer.
- D. They do not dissolve in solvents.
Answer
The correct option is They can be remolded multiple times.. This answer is correct because it matches the approved learning objective to distinguish thermosoftening polymers from thermosetting polymers in terms of behaviour when heated. (Chemistry only) in the subtopic Ceramics, polymers and composites.
Explanation
The correct option is They can be remolded multiple times.. They can be remolded multiple times. is correct because it directly supports the approved learning objective to distinguish thermosoftening polymers from thermosetting polymers in terms of behaviour when heated. (Chemistry only). This belongs to the subtopic Ceramics, polymers and composites within Using materials, so the explanation must stay tied to that curriculum context. The other options are incorrect because they either do not answer this learning objective, use a vague statement, or move away from Ceramics, polymers and composites.
Common mistake
Confusing Polymer Types
Students often confuse thermosoftening polymers with thermosetting polymers, thinking both behave the same way when heated.
Remember that thermosoftening polymers can be reshaped when heated, while thermosetting polymers do not change shape and become rigid upon heating.
