Freezing water will expand about 3% linearly as it freezes, then it will contract with a positive expansion coefficient as ice and gets colder. It can be measured using methods such as dilatometer or transducer.
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.

dL/dT = αL*L, where L is the length of the steel, T is temperature, and αL is the linear thermal expansion coefficient which for steel is about 11.0 to 13.0. That is possibly the easiest differential equation in history: (1/L)dL = (αL)dT ln(L) = αLT L = eαLT
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 (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.
yes,according to relation coefficient of linear expansion depends upon original length.
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.

The coefficient of cubical expansivity would normally be the cube of the coefficient of linear expansivity unless that coefficient is different in different directions for a material. In that case it would be the product of the linear coefficients in the different directions.

The correlation coefficient is a measure of linear association between two (or more) variables. It does not measure non-linear relationships nor does it say anything about causality.
