It is defined as close in temperature of substance
Invar (a special iron - nickel alloy) is used in pendulam instead of aluminium ,in order to decrease the expansivity.
not possible to change an area unit to linear unit
You can't convert that. You can convert from one linear unit to another linear unit, or from one square unit to another square unit, but not between linear units and square units.
A meter (metre) is a linear unit. there are no "non-linear" meters.
Linear expansivity is the increase in length per unit length per degree rise in temperature. While cubic expansivity is the increase in volume per unit in volume per degree rise in temperature.
2*linear expansitivity
It is defined as close in temperature of substance
The coefficient of cubical expansivity is a measure of how the volume of a substance changes with temperature. It is defined as three times the linear coefficient of thermal expansion. It is denoted by the symbol β and has units of K^-1.
No. The expansivity is on a per unit basis just like the specific heat or density is.

You can test the bimetallic strip's expansivity by placing it in a hot or cold environment, such as a refrigerator or a Bunsen burner. The strip that contracts or expands more has a higher expansivity than the other.

the expansion is strain e times length L or y = eL if strain is temperature related then e = CTE x temperature T where CTE is linear thermal expansion coefficient or y = CTE x L x T
