Below 0.6K the heat capacity of liquid He is well represented by the equation(adsbygoogle = window.adsbygoogle || []).push({});

Cv=(9.819 x 10^-3 K^-3)NkT^3

Given that transverse shear waves cannot propagate in a liquid, predict the phonon contribution to the heat capacity of He from the data

c=238 m/s (speed of sound in liquid He)

p=0.145 g cm^-3 (density of liquid He)
