विकल्प

• 6

• `7/2`

• `5/2`

• `7/5`

Answer 1

An ideal gas has molecules with 5 degrees of freedom. The ratio of specific heats at constant pressure (C_P) and at constant volume (C_v) is `underlinebb(7/5)`.

Explanation:

The ratio of specific heat at constant pressure (C_p) and constant volume (C_v).

`"C"_"p"/"C"_"v" = γ = (1 + 2/"f")`

where f is the degree of freedom.

`"C"_"p"/"C"_"v" = (1 + 2/5) = 7/5`
