Question

expression of linear expansion in solid ​

Answer 1

Answer:

Thermal expansion is large for gases, and relatively small, but not negligible, for liquids and solids. Linear thermal expansion is 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

Answer:

Expression for the Coefficient of Linear Expansion of Solids: ... The coefficient of linear-expansion is defined as the increase in length per unit original length at 00c per unit rise in temperature
