Monoatomic gases have three degrees of freedom due to single atoms moving in X, Y, and Z directions, while diatomic gases have five degrees of freedom, including rotation. Polyatomic gases, with more than two atoms, have six degrees of freedom, making them the most complex in terms of movement analysis.
Insights
- Monoatomic gases have three degrees of freedom due to their single-atom structure, allowing them to move freely in three directions.
- Polyatomic gases, comprising more than two atoms, exhibit six degrees of freedom, with three for translation and three for rotation, making them the most intricate in terms of movement analysis.

Degrees of Freedom in Monoatomic, Diatomic, Polyatomic Gases
- Monoatomic gases consist of single atoms, allowing movement in the X, Y, and Z directions, resulting in three degrees of freedom. Diatomic gases, composed of two atoms, have three degrees of freedom for translation and two for rotation, totaling five degrees of freedom. Polyatomic gases, with more than two atoms, possess six degrees of freedom, three for translation and three for rotation, making them the most complex in terms of movement analysis.
