The molar specific heat of a gas as given from the kinetic theory is `(5)/(2) R`. If it is not specified whether it is `C_(p) or C_(upsilon)` one could conclude that the molecules of the gasA. are definitely monoatomicB. are definitely rigid diatomicC. are definitely non-rigid diatomicD. can be monoatomic or rigid diatomic |

Answer» Correct Answer - D A monoatomic gas has 3 degree of freedom and diatomic gas has 5 degrees of freedom. For monotomic gas, `C_(upsilon) = 3/2 R and C_(p)=C_(upsilon) + R` `or C_(P) = 3/2 R + R = 5/2R` For a ditomaic gas, `C-(upsilon) =5/2 R, C_(upsilon)+R` =5/2R+ R=7/2 R` Hence we can conclude that the molecules of the gas can b monoatomc and rigid diatomic. |
