Question:

Degree of freedom for polyatomic gas is

≥4

≥6

≥5

≥7

Solution:

A diatomic molecule possesses 3 translational, 2 rotational, and 1 vibrational degree of freedom which gives a total of 6 degrees of freedom. A polyatomic gas has more than 2 atoms in one molecule of it so it must have more than or equal to 6 degrees of freedom.
