Equipartition Theorem

Postby CarolYassa2K » Fri Jan 27, 2023 12:17 pm

How do you find linear vibration degrees of freedom? What is the difference between rotational and translational degrees of freedom?

Rotational, translational, or vibrational degrees of freedom describe different ways that molecules and their atoms can move in space. The number of degrees of freedom are determined based on the structure and how the chemical can move, rotate or translate across an axis of symmetry in space based on the molecules’ symmetry. For this class, we will know the structure of the gas molecules we use. Where monogamic gas have 3/2 degrees of freedom and diatomic have 5/2 giving us the following equations:

monoatomic gas U=3/2nRT

Diatomic linear gas U=5/2nRT
