Question
- A. They become soft and can be reshaped.
- B. They decompose and lose their properties.
- C. They retain their shape and strength.
- D. They dissolve in solvents.
Answer
The correct option is They retain their shape and strength.. This answer is correct because it matches the approved learning objective to explain the difference between thermosoftening and thermosetting polymers in terms of structure. (Chemistry only) in the subtopic Ceramics, polymers and composites.
Explanation
The correct option is They retain their shape and strength.. They retain their shape and strength. is correct because it directly supports the approved learning objective to explain the difference between thermosoftening and thermosetting polymers in terms of structure. (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 and thermosetting polymers, thinking they behave the same when heated.
Remember that thermosoftening polymers can be reshaped when heated, while thermosetting polymers maintain their shape and do not melt upon reheating.
