Question

Establish the relationship between superficial and cubical expansivity of a material.​

Answer 1

Explanation:

Consider superficial expansion of the plate area. Thus the coefficient of superficial expansion is twice the coefficient of linear expansion. Relation Between α and γ: Thus the coefficient of cubical expansion is the thrice coefficient of linear expansion

Answer 2

Explanation:

Consider superficial expansion of the plate area. Thus the coefficient of superficial expansion is twice the coefficient of linear expansion. Relation Between α and γ: ... Thus the coefficient of cubical expansion is the thrice coefficient of linear expansion.
