Degrees of freedom for a diatomic gas
WebApr 3, 2024 · The total degrees of freedom for a diatomic gas molecule is said to be 5. A diatomic molecule can vibrate along the bond axis and thus a vibrational kinetic energy and a vibrational potential energy can also be present for a diatomic molecule. This means that a diatomic molecule can have 5 or 7 degrees of freedom, depending on absence or ... Weblational degrees of freedom. So for atomic gas one has γ =5/3. For diatomic molecular gas, such as most of the gas in the Earth’s atmosphere (mainly N 2 and O 2), as well as for molecular hydrogen gas in interstellar molecular clouds (H 2) the gas particles have, in addition to the three translational degrees of freedom also 2 rotational ...

WebSolution. Verified by Toppr. Correct option is B) Number of degree of freedom d=3N−1. where N is the number of atoms in a molecules. In diatomic molecules, N=2. d=3(2)−1=5. Hence diatomic molecule has 5 degrees of freedom ( 3 translational and 2 rotational). Any atom or molecule has three degrees of freedom associated with translational motion (kinetic energy) of the center of mass with respect to the x, y, and z axes. These are the only degrees of freedom for a monoatomic species, such as noble gas atoms.
