Question:
Which of the following is an intensive property?
Which of the following is an intensive property?
Show Hint
Intensive properties do not change with the amount of substance, while extensive properties are directly proportional to the amount of material.
Updated On: Feb 18, 2026
- Mass
- Melting point
- Internal energy
- Volume
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Understanding intensive and extensive properties.
Intensive properties are independent of the amount of material present, while extensive properties depend on the quantity of the substance. Melting point is an intensive property because it does not change with the amount of substance.
Step 2: Analyzing the options.
(A) Mass: Mass is an extensive property because it depends on the amount of material.
(B) Melting point: Melting point is an intensive property because it is independent of the amount of substance.
(C) Internal energy: Internal energy is an extensive property, as it depends on the quantity of material.
(D) Volume: Volume is an extensive property because it is dependent on the amount of substance.
Step 3: Conclusion.
The correct answer is (B) Melting point.
