A) I and II
B) I
C) I and III
D) I and IV
Correct Answer: D
Solution :
Cubic \[\frac{D'}{D}=\frac{V}{V-\Delta V}={{\left[ 1-\frac{\Delta V}{V} \right]}^{-1}}=1+\frac{\Delta V}{V}\] and \[\frac{D'}{D}-1=\frac{\Delta V}{V}\]) and Rhombohedral \[\frac{D'-D}{D}=\frac{\Delta V}{V}\] and \[\frac{\Delta V}{V}=\frac{p}{B}\] have all sides and all angles equal.You need to login to perform this action.
