Question

Intensive variable(s) is/are

• A. temperature
• B. volume
• C. pressure
• D. density

Hint:

If a property remains unchanged when you double the amount of substance, it is intensive.

Answer 1

The Correct Option is A, C, D

Step 1: Understanding intensive vs extensive.
Intensive properties do not depend on the amount of matter, while extensive properties depend on the size or mass of the system.
Step 2: Evaluating the options.
(A) Temperature → independent of system size → intensive.
(B) Volume → depends on quantity of matter → extensive → incorrect.
(C) Pressure → independent of amount of substance → intensive.
(D) Density → ratio (mass/volume), independent of size → intensive.
Step 3: Conclusion.
Hence, temperature, pressure and density are intensive variables.
