Why measuring scale should be made up of insulators or metals whose coefficient of linear expansion is small?
Wiki User
∙ 8y ago
Using insulators or metals with a small coefficient of linear expansion ensures that the scale does not expand or contract significantly with changes in temperature. This helps maintain the accuracy of the measurements taken using the scale, as it minimizes any distortions due to thermal expansion. Additionally, insulators or materials with low thermal expansion are more stable and less prone to warping, which further ensures the reliability of the scale.

Linear expansion apparatus?
A linear expansion apparatus is used to measure the change in length of a material in response to a change in temperature. It typically consists of a sample material mounted between two supports, with a mechanism to control the temperature. By measuring the change in length as the temperature changes, the coefficient of linear expansion of the material can be determined.
What is the relation between the coefficient of linear and superficial and volume expansion respectively?
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.
What is the relationship of coefficient linear expansion to actual expansion?
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.
A material has a coefficient of volume expansion of 60×10^-6/degree celsius. What is its coefficient of expansion?
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.
What is the coefficient of linear expansion of mercury?
The coefficient of linear expansion of mercury is 0.000181 per degree Celsius.
What is the cubical coefficient of thermal expansion for metals?
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.

What is meant by the cofficient of linear and superficial expansion?
The coefficient of linear expansion measures how much a material expands in length when heated, while the coefficient of superficial expansion measures how much a material expands in area when heated. Both coefficients are used to quantify how materials respond to changes in temperature.
Why is it necessary to know the coefficient of linear expansion of solids?
Knowing the coefficient of linear expansion of a solid is important because it allows us to predict how much the solid will expand or contract when subjected to changes in temperature. This information is crucial for designing structures and systems that can accommodate thermal expansion without causing damage or inefficiencies.
