1. Fill in the blanksName of gasDegrees of freedomInternal energyCVCP?Monoatomic3......\(\frac{3}{2}R\)...........Diatomic rigid.......\(\frac{5}{2} RT\).......\(\frac{7}{2}R\)........ 2. What happens to the value of ratio of specific heat capacity, if we consider all rotational degrees of freedom of a 1-mole diatomic molecule? |

Answer» 1.
2. Total degrees of freedom = 3 (trans) + 3 (Rot) = 6 ∴ CV = 3R, CP = 4R Ratio of specific heat γ = \(\frac{4}{3}\) Ratio of specific heat capacity decreases. |
