Kinetic Theory of Gases: Practice Problem & Solution

Solution Explained:

To solve this problem, we apply the core principles of Kinetic Theory of Gases. Understanding the underlying formula is key to arriving at the correct answer below:

According to the law of equipartition of energy, the average energy associated with each degree of freedom per molecule is $\frac{1}{2}kT$. For a molecule with $n$ degrees of freedom, the total mean energy is $\frac{n}{2}kT$.
