(N/A) The degree of freedom is defined as the number of independent ways in which a molecule of a gas can possess energy or undergo motion.
The degree of freedom depends on the following factors:
$(1)$ The number of atoms in the molecule (atomicity).
$(2)$ The temperature of the gas (which determines the activation of vibrational modes).
Mathematically,the total number of independent quadratic terms in the expression for the total energy of a molecule is called its degree of freedom $(f)$.
