Vedclass · Answer

(B) The magnitude of a physical quantity is an intrinsic property of the object or phenomenon being measured. While the numerical value $(n)$ and the unit $(u)$ change depending on the system of units used,the product of the numerical value and the unit remains constant,i.e.,$n_1u_1 = n_2u_2 = 	ext{constant}$. Therefore,the actual magnitude of the physical quantity itself is independent of the method or system of measurement chosen.

Substance	Atomic Mass $(u)$	Density $(10^3\,kg\,m^{-3})$
Carbon (diamond)	$12.01$	$2.22$
Gold	$197.00$	$19.32$
Nitrogen (liquid)	$14.01$	$1.00$
Lithium	$6.94$	$0.53$
Fluorine (liquid)	$19.00$	$1.14$
