Question

difine coefficient of volume expansion and write a relation for it​

Answer 1

Answer:

Thermal expansion is the increase, or decrease, of the size (length, area, or volume) of a body due to a change in temperature. ... The change in volume due to thermal expansion is ΔV = βVΔT, where β is the coefficient of volume expansion and β ≈ 3α.

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.
