PhysicsThermal Properties of MatterMHT CET

The coefficient of linear expansion of crystal in one direction is and that in other two directions perpendicular to it is . The coefficient of cubical expansion is

Answer: (C)

Solution

The volume coefficient is the sum of the linear coefficients along the three perpendicular directions: $γ = α_1 + α_2 + α_2 = α_1 +
