Question

Given below are two statements: one is labelled as Assertion A and the other is labelled as Reason R Assertion A: Mass and volume are extensive properties.
Reason R: The ratio of mass to volume is also an extensive property. In the light of the above statements, choose the most appropriate answer from the options given below

• A. Both A and R are correct and R is the correct explanation of A.
• B. Both A and R are correct but R is NOT the correct explanation of A.
• C. A is correct but R is not correct.
• D. A is not correct but R is correct.

Hint:

Concept Tip: Extensive properties depend on the amount of matter (mass, volume), whereas intensive properties do not depend on amount (density, temperature).

Answer 1

The Correct Option is C

Concept:
Properties are classified as:
• Extensive properties
• Intensive properties
Step 1:
Extensive properties depend upon amount of matter. Examples:
• Mass
• Volume Thus Assertion A is correct.
Step 2:
\[ \frac{\text{Mass}}{\text{Volume}}=\text{Density} \] Density does not depend upon amount of matter.
Step 3:
Density is an intensive property. Therefore Reason R is incorrect.
Step 4:
\[ \boxed{\text{A is correct but R is not correct}} \] \[ \boxed{\text{Correct Option = (3)}} \]
