Assertion (A) : The magnitude of volume ...

Assertion (A) : The magnitude of volume of any liquid is equal to the magnitude of its mass what measured in CGS system.
Reason (R ) : Density of the liquid = mass of the liquid `xx` volume of the liquid.

A

(a) Both A and R are true and R is the correct explaanation of A.

B

(b) Both A and R are true, but R is not the correct explanation of A.

C

(c ) A is true but R is false.

D

(d) Both A and R are false.

Text Solution

Verified by Experts

The correct Answer is:
D
The magnitude of volume of any liquid is not equal to the magnitude of its mass when measured in CGS system. Only in case of water the magnitude of volume and mass are equal. So, A is incorrect. Density of substance= `"mass of the substance"/"`volume of the substance"
So, R is also wrong.
Both A and R are incorrect.
