Vedclass · Answer

(D) The density of a solid is defined as the ratio of mass to volume. In $SiC$ (Silicon Carbide),the crystal lattice is fixed. Option $A$ changes the mass of the unit cell. Option $B$ (Vacancy defect) involves the loss of atoms,which decreases the mass while the volume remains constant,thus changing the density. Option $C$ involves substituting atoms with different atomic masses ($Ge$ has a different mass than $Si$ or $C$),which changes the mass of the unit cell. Option $D$ involves interchanging the positions of $Si$ and $C$ atoms within the existing lattice. Since the total number of $Si$ and $C$ atoms remains the same,the total mass of the unit cell remains unchanged. Therefore,the density remains constant.
