Which statements are correct about degrees of freedom ?

(A) A molecule with n degrees of freedom has n2 different ways of storing energy.

(B) Each degree of freedom is associated with 12 RT average energy per mole.

(C) A monatomic gas molecule has 1 rotational degree of freedom where as diatomic molecule has 2 rotational degrees of freedom.

(D) CH4 has a total of 6 degrees of freedom.

Choose the correct answer from the options given below :

Multiple Choice Options

  • A (B) and (C) only
  • B (B) and (D) only
  • C (A) and (B) only
  • D (C) and (D) only

Step-by-Step Verified Solution

Statement A is incorrect, statement B is correct by equipartition of energy. Statement C is incorrect as monoatomic does not have any rotational degree of freedom and CH4 is a polyatomic gas so it has 6 degree of freedom. So only B and D are correct.
