$3RT$

Vedclass · Answer

(A) According to the law of equipartition of energy,each degree of freedom contributes $\frac{1}{2}RT$ to the internal energy of one mole of a substance.$A$ solid atom can be modeled as a three-dimensional harmonic oscillator.For a three-dimensional harmonic oscillator,there are $3$ degrees of freedom for kinetic energy and $3$ degrees of freedom for potential energy,totaling $6$ degrees of freedom.Therefore,the total internal energy $U$ for one mole of a solid is $U = 6 	imes (\frac{1}{2}RT) = 3RT$.
