The molar heat capacity for a metal is roughly equal to three times this quantity, according to the Law of Dulong and Petit. 
The molar heat capacity for a metal is roughly equal to three times this quantity, according to the Law of Dulong and Petit. Like entropy, it is most often expressed in joules per mole Kelvin. The product of this quantity and temperature also appears in the Nernst equation. In the Arrhenius equation, the activation energy divides both this quantity and temperature. It is equal to the product of Boltzmann's constant and Avogadro's number. For 10 points, give this constant equal to about 8.31 joules per mole Kelvin, usually symbolized R.
