Debye temperature for diamond is 2230 K. Calculate the frequency of highest possible lattice vibration in diamond and its molar heat capacity at 20 K.
We are given: * Debye temperature (θD) = 2230 K * Temperature (T) = 20 K * Goal: 1. Find the maximum lattice vibration frequency (Debye frequency) 2. Calculate molar heat capacity at 20 K using Debye model. --- ### (1) Frequency of highest possible lattice vibration The Debye temperature is related to the maximum (Debye) frequency by: $$ \theta_D = \frac{h \nu_D}{k_B} ______ ___ ____ _____ ___ _________ ________ _______ __________ ___ _____ ___.
