According to the Dulong-Petit law, at high temperatures, the heat capacity of a solid approaches:

The NaCl unit cell is a face-centered cubic (FCC) lattice with 4 Na+ and 4 Cl− ions per unit cell, leading to:

The Hall coefficient is defined as:
where is the Hall voltage, is the current density, and is the applied magnetic field.

The volume of the reciprocal unit cell is given by:
