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
Assertion A states that mass and volume are extensive properties. An extensive property depends on the amount of matter in a substance.
Therefore, Assertion A is correct.
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.
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.
