Question
- A. It has a higher melting temperature than borosilicate glass.
- B. It is made from sand, sodium carbonate, and limestone.
- C. It is primarily used for high-strength applications.
- D. It is resistant to thermal shock.
Answer
The correct option is It is made from sand, sodium carbonate, and limestone.. This answer is correct because it matches the approved learning objective to describe soda-lime glass as made by heating sand, sodium carbonate and limestone. (Chemistry only) in the subtopic Ceramics, polymers and composites.
Explanation
The correct option is It is made from sand, sodium carbonate, and limestone.. It is made from sand, sodium carbonate, and limestone. is correct because it directly supports the approved learning objective to describe soda-lime glass as made by heating sand, sodium carbonate and limestone. (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.
