The unit of linear expansivity, also known as coefficient of linear expansion, is typically expressed in reciprocal temperature units, such as per degree Celsius (°C⁻¹) or per Kelvin (K⁻¹). It quantifies how much a material expands or contracts in response to changes in temperature, specifically describing the change in length per unit length for a one-degree change in temperature. For example, a linear expansivity of 10 x 10⁻⁶ °C⁻¹ indicates that a 1-meter length of the material would expand by 10 micrometers for each degree Celsius increase in temperature.
It is defined as close in temperature of substance
Linear expansivity of solids is crucial in various applications, such as engineering and construction, where materials expand and contract with temperature changes. This property is considered when designing bridges, railways, and buildings to prevent structural damage. Additionally, it is important in manufacturing processes, such as metalworking and glass production, where precise dimensions are required. Understanding linear expansivity also aids in selecting materials for electronic components to ensure reliability under varying thermal conditions.
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.
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.

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.

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.

A meter (metre) is a linear unit. there are no "non-linear" meters.
