Question
- A. They can be reshaped when heated
- B. They maintain their shape when heated
- C. They are always more expensive than thermosetting polymers
- D. They do not melt
Answer
The correct option is They can be reshaped when heated. This answer is correct because it matches the approved learning objective to explain that polymer properties depend on the monomers and the conditions used to make them. (Chemistry only) in the subtopic Ceramics, polymers and composites.
Explanation
The correct option is They can be reshaped when heated. They can be reshaped when heated is correct because it directly supports the approved learning objective to explain that polymer properties depend on the monomers and the conditions used to make them. (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
Misunderstanding Polymer Properties
Students often think that all polymers have the same properties regardless of their monomers and production conditions.
Emphasize that polymer properties vary significantly based on the specific monomers used and the conditions under which they are synthesized.
