Hi, this is my first time using this forum. I have a question dealing with entropy and thermodynamics. Here goes: According to Debye’s law, the molar heat capacity at constant volume of a diamond varies with temperature according to the relation Cv = (12*pi^4*R / 5) x (T / TD)^3 where TD = 2230 K. For a diamond of mass 1. 20 g, what is its entropy change when it is heatedat constant volume from 10. 0 K to 350 K? The molar mass of carbon is 12. 0 g/mol. I know Ih ave to first find the molar mass, but I am not sure of which form of the entropy equation to use. Any help is appreciated.
