Homework Statement
A solid's thermal expansion coefficient is defined as
δ= [itex]\left(\frac{1}{V}\frac{∂V}{∂T}\right)[/itex]
In the Debye model and at the low-temperature limit, show that δ is a positive quantity and is proportional to [itex]T^{3}[/itex]. At the high-temperature limit, show that δ is still positive but does not depend on temperature anymore.
Homework Equations
δ= [itex]\left(\frac{1}{V}\frac{∂V}{∂T}\right)[/itex]
The Attempt at a Solution
I don't even know how to express volume as a function of temperature!
