A crystal has a coefficient of linear expansion of 12*10^-6 °C in one direction and 24*10^-6 °C in every direction at right angles to it. Then the coefficient of cubical expansion of the crystal is 1.

It is different in different directions for anisotropic materials like crystals. The coefficient of cubical expansion is the change in volume per unit volume per degree change in temperature. It is the sum of the coefficients of linear expansion in all three Show more…

The coefficient of linear expansion of crystal in one direction is $\alpha_{1}$ and that in every direction perpendicular to it is $\alpha_{2}$. The coefficient of cubical expansion is (a) $\alpha_{1}+\alpha_{2}$ (b) $2 \alpha_{1}+\alpha_{2}$ (c) $\alpha_{1}+2 \alpha_{2}$ (d) none of these
For a certain crystal, the unit cell axial lengths are found to be $a=5.62 \AA, b=7.41$ $\AA$ and $c=10.13 \AA$. The three coordinate axes are mutually perpendicular. The crystal system to which the crystal belongs is (a) tetragonal (b) orthorhombic (c) monoclinic (d) cubic
