Debye Heat Capacity

  1. Nov 18, 2006 #1
    I am currently re-reading an old text book on thermal physics and they have listed the final result for calculating the Debye Heat Capacity as

    C =9R(T/ThetaD)^3*Integral((z^4*e^z dz)/(e^z-1)^2, 0-->ThetaD/T)

    But they fail to mention what the R in this equation is, Could some one please tell me what R is?

    Thanks.

    Gas constant. The one in PV = nRT
    R = 8.314 Joule/mol°K
