1. Consider that a two-dimensional system of area A is filled with N number of

triatomic molecules. A triatomic molecule will have several degrees of freedom.

For simplicity, assume that each molecule of mass m to be a Harmonic oscillator,

which has two characteristic frequencies, w, and w₂, respectively. Considering

only translational and vibrational degrees of freedom, calculate the partition

function of the system. Then calculate the entropy and the two-dimensional

pressure of this system.
