Question

relation between linear coefficient and volume coefficient

Answer 1

Hello!

3α = γ

Here α is the coefficient of linear expansion


γ is the coefficient of Volume expansion or superficial expansion

hope helped!

Answer 2

Coefficient of Linear Expansion : It is the change in length per unit length per unit change in temperature.
∴α= (dl/l )1/dT

Coefficient of Volume Expansion:It is the change in volume per unit volume per unit change in temperature.
∴γ= (dV/V )1/dT
**********************************************
Relation between linear coefficient and volume coefficient is :
γ=3α
