Assertion : The number of degrees of freedom of non-linear triatomic molecule is 6 . Reason : Triatomic molecule has three translational degrees of freedom and three rotational degrees of freedom.
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but reason is correct.
Explanation:
The assertion and reason correctly describe the degrees of freedom for triatomic molecules. They have 3 translational degrees of freedom and 3 rotational degrees of freedom. So correct option is (1).

Assertion : Equal masses of helium and oxygen gases are given equal quantities of heat. There will be a greater rise in the temperature of helium compared to that of oxygen. Reason : The molecular weight of oxygen is more than the molecular weight of helium.
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but reason is correct.
Explanation:
Helium is a monatomic gas, while oxygen is diatomic. Therefore, the heat given to helium will be totally used up in increasing the translational kinetic energy of its molecules; whereas the heat given to oxygen will be used up in increasing the translational kinetic energy of the molecule and also in increasing the kinetic energy of rotation and vibration. Hence temperature rise of helium is more. Option (2) is correct.

Assertion : The molecule of a monoatomic gas has three degrees of freedom at room temperature. Reason : The molecule of a diatomic gas has five degree of freedom.
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but reason is correct.
Explanation:
A monoatomic gas molecule (like \(\mathrm{He}\) ) consists of single atom. It has translational motion in any direction in space. Thus, it has 3 translational degrees of freedom. The molecules of a diatomic gas (like \(\left.\mathrm{O}_{2}, \mathrm{CO}_{2}, \mathrm{H}_{2}\right)\) cannot only translate but also rorate about any one of the three co-ordinate axes. Hence, it can have two rotational degrees of freedom. Thus, a diatomic molecule has 5 degrees of freedom: 3 translational and 2 rotational.

The temperature of argon, kept in a vessel, is raised by \(1^\circ C\) at a constant volume. The total heat supplied to the gas is a combination of translational and rotational energies. Their respective shares are
1 \(40 \%\) and \(60 \%\)
2 \(60 \%\) and \(40 \%\)
3 \(505\) and \(50{\text{ }}\% \)
4 \(100 \%\) and \(0 \%\)
Explanation:
Argon is a monoatomic gas so it has only translational energy. Translational : Rotational \(=100 \%: 0 \%\)
