Correct option is D
coefficient of volume expansion of crystal is γ=αx+αy+αz αx,αy,αz coefficient of linear expansion of crystal along mutually perpendicular directions γ=9×10−5+12×10−5+7×10−5 γ=28×10−5/KSimilar Questions
The coefficient of expansion of a crystal in one direction (x-axis) is 2.0x 10-6 K-1 and that in the other two perpendicular (y-and z-axes) direction is 1.6 x 10-6 K-1 What is the coefficient of cubical expansion of the crystal?
