What is interatomic force ? .

According to Dulong & Petits law, molar heat capacity of solids at room temperature is nearly equal to 3R. This can be explained using law of equipartition. Each atom of solid is boned to neighboring atoms by interatomic forces. Each atom can vibrate about its equilibrium positum. So each atom has 6 degrees of freedom. But in relaity, the molar heat capacity of solids varies. with temperature as shown in figure. At low temperature, the heat capcities decrease with decreasing temperature. This is due to the fact that variational degrees of freedom are frozen out at low temperatures. Selec the correct statement(s).
