Question

What are the coefficients of linear expansion and volume expansion?
​

Answer 1

Answer:

The relationship between the area and linear thermal expansion coefficient is given as the following: αA=2αL α A = 2 α L . Just like the linear expansion coefficient, the area thermal expansion coefficient works as an approximation over a narrow temperature interval only.

Answer 2

Explanation:-

For isotropic materials the coefficients linear thermal expansion α and volumetric thermal expansion αV are related by αV = 3α. For liquids usually the coefficient of volumetric expansion is listed and linear expansion is calculated here for comparison.
