Question
- A. Thermosoftening polymers can be reshaped when heated, while thermosetting polymers cannot.
- B. Thermosetting polymers can be reshaped when heated, while thermosoftening polymers cannot.
- C. Thermosoftening polymers are always stronger than thermosetting polymers.
- D. Thermosetting polymers are always weaker than thermosoftening polymers.
Answer
Thermosoftening polymers can be reshaped when heated, while thermosetting polymers cannot.
Explanation
Thermosoftening polymers can be melted and reshaped multiple times, whereas thermosetting polymers undergo a chemical change when heated, making them rigid and unable to be reshaped.
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 cannot be reshaped after they have set.
