Direction (Q. Nos. 9) This sectionis based on statement I and Statement II. Select the correct answer from the code given below.
Q.
Statement I : Cv value of helium (He) is always 3/2R but Cv value of hydrogen (H2) is 3/2R at low temperature, 5/2R at moderate temperature and more than 5/2R at higher temperature.
Statement II : At lower temperature, only translational degree of freedom contributes to heat capacity while at higher temperature, rotational and vibrational degrees of freedom also contribute to heat capacity.
- a)Both Statement I and Statement II are correct and Statement II is the correct explanation of Statement I
- b)Both Statement I and Statement II are correct and Statement II is not the correct explanation of Statement I
- c)Statement I is correct but Statement II is incorrect
- d)Statement II is correct but Statement I is incorrect
Correct answer is option 'A'. Can you explain this answer?

In case of helium (monoatomic gas) we have only three degrees of freedom which correspond to three translational motion so the total heat capacity will increase. The contributors by vibrational motion are not appreciable at low temperature but increase from 0 to R when temperature increases.
CV=−f(R)/2
CV=-f(R)2, where f is the degree of freedom. At low temperature only translational motion is considered and f=3
∴CV=3R/2
f=3.∴CV=3R2 At moderate temperature both translational and rotational motions are considered.
f=3+2
f=3+2 (3-translational and 2 rotational).
∴CV=5R/2
∴CV=5R2. At still high temperature translational, rotational and vibrational motions are considered.
f=3+2+2
f=3+2+2 (3-translatinal , 2-rotational, 2-vibrational).
∴CV=7R/2
CV=−f(R)/2
CV=-f(R)2, where f is the degree of freedom. At low temperature only translational motion is considered and f=3
∴CV=3R/2
f=3.∴CV=3R2 At moderate temperature both translational and rotational motions are considered.
f=3+2
f=3+2 (3-translational and 2 rotational).
∴CV=5R/2
∴CV=5R2. At still high temperature translational, rotational and vibrational motions are considered.
f=3+2+2
f=3+2+2 (3-translatinal , 2-rotational, 2-vibrational).
∴CV=7R/2
