Cv Value For Triatomic Gas. Monatomic is a combination of two words “mono” and “atomic” means a single atom. This is cool because now each term is a function of t only !
For monoatomic gas (f=3) c v =3r/2. In any case, the molar heat capacity of no triatomic gas is 7r/2 except possibly at one single temperature. | edurev chemistry question is disucussed on edurev study group by 150 chemistry students.
Γ=5/3 for diatomic gas (f=5) c v =5r/2.
| edurev chemistry question is disucussed on edurev study group by 150 chemistry students. You can also find a full explanation on how they have been derived in the mentioned reference papers (4, 8, 9). Γ = c p c v = 1 + 2 f. In the gaseous phase at sufficiently high temperatures, all the chemical elements are monatomic gases.
