Question

coefficient of linear expansion (a)=___×coefficient of volume expansion​

Answer 1

Explanation:

LINEAR THERMAL EXPANSION—THERMAL EXPANSION IN ONE DIMENSION

The change in length ΔL is proportional to length L. The dependence of thermal expansion on temperature, substance, and length is summarized in the equation ΔL = αLΔT,where ΔL is the change in length L, ΔT is the change in temperature, and α is the coefficient of linear expansion, which varies slightly with temperature.

Answer 2

Coefficient of linear expansion$( \alpha ) = \frac{1}{3}$×coefficient of volume expansion

━━━━━━━━━━━━━━━━━━━━━━━━━━━━

$\alpha = 3 \gamma \\ \alpha = \frac{ 1 }{3} \times \gamma$
