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.

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.
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?
-39 degrees celsius to 450 degrees celsius
Does coefficient of linear expansion depend on length?
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.
Linear expansion apparatus?

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.
Does the coefficient of linear expansion depends upon length?
yes,according to relation coefficient of linear expansion depends upon original length.

What measures the strength of the linear relationship between two quantitative variables?
The strength of the linear relationship between two quantitative variables is measured by the correlation coefficient. The correlation coefficient, denoted by "r," ranges from -1 to 1. A value of 1 indicates a perfect positive linear relationship, -1 indicates a perfect negative linear relationship, and 0 indicates no linear relationship. The closer the absolute value of the correlation coefficient is to 1, the stronger the linear relationship between the variables.
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?
By knowing the coefficient of linear expansion of solids, you can determine how a solid reacts to temperature. Everything reacts to thermal expansion. For instance, a concrete bridge expands when hot, and with the formula for expansion and the coefficient for it, you know just how much that concrete expands and you can plan and build accordingly. That saves lives.
