Time management is very much important in IIT JAM. The eduncle test series for IIT JAM Mathematical Statistics helped me a lot in this portion. I am very thankful to the test series I bought from eduncle.

A and B are both classical ideal gases of diatomic molecules. The point-like atoms in A are bonded rigidly to form diatomic molecules while in B they are connected by bonds of finite stiffness. The ra- tio of the specific heat per molecule at constant volume of gas A to gas B is (a) I (c) 6/5 II Se] (b) 5/7 (d) 3/4

Ans is (b) Because in A there are 5 degree of freedom where 3 translation and 2 rotational so Cv=5/2 kt and in B there are 6 degree of freedom where 3 trans , 2 rotational and 1 vibra so E= 5/2KT + KT= 7/2KT so Cv=7/2 kt so ratio is 5/7
what does "bond of finite stiffness means"?
It means the structure is assumed to be elastic in nature it is just giving you additional information only.
