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
Extensive Properties Analysis: Mass, Volume, and Density
Assertion Analysis
Assertion A states that mass and volume are extensive properties. An extensive property depends on the amount of matter in a substance.
- Mass is the total amount of matter in an object, hence it is an extensive property.
- Volume is the space occupied by the matter, which also depends on the amount of matter, making it an extensive property.
Therefore, Assertion A is correct.
Reason Analysis
Reason R states that the ratio of mass to volume is also an extensive property. The ratio of mass to volume defines density ($ \rho $).
Density is calculated as: $ \rho = \frac{Mass}{Volume} $ Density is an intensive property. Its value does not change with the amount of substance. For example, the density of water is constant regardless of whether you have a small cup or a large bucket of it.
Therefore, Reason R is incorrect.
Conclusion
Since Assertion A is correct and Reason R is incorrect, the correct option is that A is correct but R is not correct.
This corresponds to Option 3: A is correct but R is not correct.
