Which of the following can be determined using Differential Scanning Calorimetery:
Show Hint
DSC = Heat. If the property involves temperature changes (melting, boiling, crystalizing), DSC can measure it!
Updated On: May 28, 2026
- A, B Only
- A, B, C Only
- B, C, D Only
- A, B, D Only
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Concept
Differential Scanning Calorimetry (DSC) measures the heat flow into or out of a sample as it is heated or cooled.
Step 2: Meaning
It is used to study thermal transitions where the sample absorbs or releases energy.
Step 3: Analysis
DSC can determine Crystallization temperature (A) and Oxidation temperature (B) by measuring exothermic/endothermic peaks. It is widely used to study Polymorphism (C) as different forms have different melting points. Refractive index (D) is an optical property, not a thermal one.
Step 4: Conclusion
Only A, B, and C are thermal properties measurable by DSC.
Final Answer: (B)
