A metallic solid undergoes Frenkel defect. Its original mass, volume and density are (M₀, V₀ ) and (D₀ ) respectively. After Frenkel defect the mass, volume and density are (M, V ) and (D ) respectively. The variations of (M, V ) and (D ) after Frenkel defect are
Options
- A(M=M₀, V=V₀, D=D₀ )
- B(M < M₀, V < V₀, D < D₀ )
- C(M>M₀, V=V₀, D>D₀ )
- D(M=M₀, V D₀ )
Correct answer
A. (M=M₀, V=V₀, D=D₀ )
Step-by-step solution
In Frenkel defect, atoms remain within the solid crystal. Only one vacancy is created. Density remains the same. Thus, (M=M₀, V=V₀ ) and (D=D₀ ). Hence, the correct option is (a).
