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.

yes,according to relation coefficient of linear expansion depends upon original length.

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..
