MCQ
Assertion : Mass and volume are extensive properties.
Reason : Mass / volume is also an extensive parameter.
  • A
    If both Assertion and Reason are correct and the Reason is a correct explanation of the Assertion.
  • B
    If both Assertion and Reason are correct but Reason is not a correct explanation of the Assertion.
  • ✓
    If the Assertion is correct but Reason is incorrect.
  • D
    If both the Assertion and Reason are incorrect.
✓

Answer

Correct option: C.
If the Assertion is correct but Reason is incorrect.
c
The properties of a system which depend upon quantity of matter contained in it are called extensive properties, e.g., mass, volume, heat capacity etc. But mass / volume = density is an intensive property as density does not depend upon quantity of matter in a system.
