Debye's T3 Law. At very low temperatures the molar heat capacity of rock salt varies with temperature according to Debye's T3law: C= kT3/O3 Where k = 1940J/mol' K and 0= 281 K.
(a) How much heat is required to raise the temperature of 1.50 mol of rock salt from 10.0 K40.0 K? (Hint Use Eq. (17.18) in the form dQ = nC dT and integrate.)
(b) What is the average molar heat capacity in this range?
(c) What is the true molar heat capacity at 40.0 K?
