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.
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.
Invar (a special iron - nickel alloy) is used in pendulam instead of aluminium ,in order to decrease the expansivity.
what is anther name for the y term in a linear equation
no
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
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.

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.
No. The expansivity is on a per unit basis just like the specific heat or density is.
The term Linear Ulcer refers to an ulcer with a particular Linear shape. Medically, the term Linear describes a lesion with a line-like appearance.
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

No. Thermal stress of a body can never be zero. It is so because for a given body, Young's modulus of it can't be zero, linear expansivity of it can't be zero and for a given temperature change, also the change in temperature can't be zero. But for some bodies made of substances like inver, whose thermal expansivity is very very small, the stress is negligible and can be neglected.
The term "linear line" is redundant; lines are necessarily linear, since linear means in the form of a line.
