1. The problem statement, all variables and given/known data
We are looking at the molar heat capacity, Cv, of copper over temperatures from 1-300K
After plotting the numbers and looking at T from 1-15K, then fitting that to a curve. We have to find what the constants \beta and \gamma are in ...
Cv=\gammaT + \betaT_{3}
Where Cv= molar heat capacity
T = temperature
\gamma and beta are constants.
Using CurveFit I found
\gamma = 7.11E-04
\beta = 4.78E-05
The question asks to find the limiting value of \ThetaD which is the Debyne temperature.
It also asks what important information is contained in \gamma (I think its electron concentration but wanted to confirm).
And what is the dominant contribution to Cv at low temperature (I would \beta as it is obviously dominant).
