# Question: the specific heat capacity of solids at low temperatures is...

###### Question details

The specific heat capacity of solids at low temperatures is given by the Debye law:

The quantity A is a constant equal to and is the Debye temperature, equal to 320 K fo NaCl.

(a) What is the molar specific heat capacity at a constant volume of NaCl at 10 K and at 50 K?

(b) How much heat is required to raise the temperature of 2 kilomoles of NaCl from 10 K to 50 K at constant volume?

(c) What is the mean specific heat capacity at a constant volume over this temperature range?
