Question

The ratio of the degrees of freedom of monatomic and diatomic gas molecules is:

• A. 5:7
• B. 3:5
• C. 3:4
• D. 5:6

Hint:

Monatomic gases have only translational motion, while diatomic gases have translational and rotational motion, leading to more degrees of freedom.

Answer 1

The Correct Option is B

For monatomic gases, the degrees of freedom are 3 (translational degrees of freedom). For diatomic gases, there are 5 degrees of freedom (3 translational + 2 rotational degrees of freedom). Thus, the ratio of the degrees of freedom for monatomic to diatomic gas molecules is: \[ \frac{3}{5} \] Therefore, the correct answer is 3:5 .
