At waht temp will the heat capactiy at constant volume of a substance achieve one third of its classical value of 3R? Express in terms of Einstein temperature Te.
3R = 24.9 J/ mol K
R = 8.314 J / mol K = [tex] 3R (\frac{Te}{T})^2 \frac{e^\frac{Te}{T}}{e^\frac{Te}{T} - 1} [/tex]
But i don't know waht the Te for a subtance is though? Te = H nu / k
i don't know Nu though...
