# Cv Value For Triatomic Gas

### Assume that the contribution of vibrational degree of freedom is 75%:a)1.222b)1.18c)1.121d)1.33correct answer is option 'b'.

Cv value for triatomic gas. For linear polyatomic gases (such as co_2 or n_2o): If the gas x obeys van der waal's equation and if the value of a = 1. Now you begin with the gas at atmospheric pressure (760 torr) and then add gas to increase the pressure inside the bottle by a small amount, say 1.5% (11.4 torr).

Furthermore, the molecule can vibrate along its axis. Trioxygen (ozone) and carbondioxide are triatomic gases. The ratio of the specific heats γ = c p /c v is a factor in adiabatic engine processes and in determining the speed of sound in a gas.

, the value of ‘x’ is, x=3/2 r. The constant pressure specific heat is related to the constant volume value by c p = c v + r. I am within ideal gas approximation range if that helps.

C v for a gas. Due to which the specific heat of gas can have any value between 0 and ∞. You have a large bottle fitted with a gas inlet and a pressure gauge attached to a stopper in the neck of the bottle, figure 1.

(vii) for triatomic gas (γ) = c p /c v = 8r/6r = 1.33 all the best & good luck !!. The ratio between cp and cv is the specific heat ratio, γ. Γ=5/3 for diatomic gas (f=5) c v =5r/2.

Can you explain this answer? Γ=7/5 for triatomic gas linear structural (f=7) c v =7r/2. In any case, the molar heat capacity of no triatomic gas is 7r/2 except possibly at one single temperature.
