The coefficient of linear expansion for aluminum is approximately 22.2 x 10^-6 per degree Celsius. This means that for every degree increase in temperature, aluminum will expand by 22.2 x 10^-6 of its original length.
The coefficient of linear expansion (α) is one-third of the coefficient of superficial expansion (β), and the coefficient of superficial expansion is one-third of the coefficient of volume expansion (γ). This relationship follows from the dimensional analysis of the expansion coefficients in the respective directions.
The coefficient of linear expansion is a constant value that quantifies how much a material expands per degree Celsius increase in temperature. The actual expansion of an object can be calculated by multiplying the coefficient of linear expansion by the original length of the object and the temperature change.
The coefficient of volume expansion is the triple of the linear expansion coefficient. So with a volume expansion coefficient of 60×10^-6/°C, the linear expansion coefficient would be 20×10^-6/°C.

No, the coefficient of linear expansion does not depend on the initial length of the material. It is a material property that remains constant regardless of the length.

Since most metals are isotropic, the cubical coefficient of expansion is three times the linear coefficient of expansion. The linear coefficient of expansion is obtained from measurement and tables for the specific material which are readily available.

Aluminum has a higher thermal expansion coefficient than copper because its crystal structure allows for larger atomic movements when heated. This results in a greater expansion of aluminum compared to copper when exposed to heat. Additionally, aluminum has a lower density and stronger interatomic bonds, leading to a higher degree of expansion when heated.
Linear expansion apparatus is the apparatus used to measure the objects to these following properties: -> coefficient linear expansion -> coefficient thermal expansion -> specific gravity -> specific heat -> thermal conductivity -> thermal resistivity -> breaking strength and many others..
The coefficient of linear expansion measures how much a material expands in length when heated, while the coefficient of superficial expansion measures how much a material expands in area when heated. Both coefficients are used to quantify how materials respond to changes in temperature.
