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?
detailed solution
Correct option is D
Coefficient of cubical expansion isγ=αx+αy+αz=αx+2αy ∵αy=αz=2.0×10−6+2×1.6×10−6=5.2×10−6K−1Hence the correct choice is (4).Talk to our academic expert!
