The ratio of the specific heats Cp / Cv = γ in terms of degrees of freedom (n) is given by

1. (1 + n / 3)
2. (1 + 2 / n)
3. (1 + n / 2)
4. (1 + 1 / n)

Correct answer: (1 + 1 / n)

Solution

The ratio of specific heats γ = Cp / Cv is derived as 1 + (2/n), where n is the number of degrees of freedom. This matches option D.
