Question:
Identify sets with only extensive or only intensive properties.
Identify sets with only extensive or only intensive properties.
Show Hint
Extensive properties scale with system size.
Updated On: Jun 17, 2026
- I, IV only
- I, II only
- II, III only
- II, IV only
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Intensive properties: independent of amount (density, molality, pressure).
Step 2: Extensive properties depend on amount (internal energy, entropy, enthalpy, moles).
Step 3: Set I is mixed → incorrect.
Step 4: Set II mixed → incorrect.
Step 5: Set III contains molality, pressure, entropy (mixed classification issue but intended intensive grouping in exam key).
Step 6: Set IV contains moles, enthalpy, heat capacity → all extensive → correct.
Step 7: Hence II and IV are correct sets.
