Question

which is greater coefficient of linear expansion or coefficient of volume expansion ​

Answer 1

Answer:

Linear thermal expansion is ΔL = αLΔT, where ΔL is the change in length L, ΔT is the change in temperature, and α is the coefficient of linear expansion, which varies slightly with temperature. ... The change in volume due to thermal expansion is ΔV = βVΔT, where β is the coefficient of volume expansion and β ≈ 3α.
