IIT Jee Problem: consider two daitomic games A and B at some temperature T.

Consider, two ideal diatomic gases A and B at some temperature T. Molecules of the gas A are rigid, and have a mass m. Molecules of the gas B have an additional vibrations mode, and have a mass m/4 . The ratio of the specific heats ( C_(V)^(A) and C_(V)^(B) ) of gas A and B, respectively is:

Consider two diatomic ideal gases A &B at some temperature T. Molecules of A rigid and have mass 2m. Molecules of B have vibrational modes in addition and have mass m.The ratio of the specific heats ( C_(v) ^(4) & C_(v) ^(B)) of gas A &B,if both the molecules have planar structure is :

If for two gases of molecular weights M_(A) and M_(B) at temperature T_(A) and T_(B) , respectively, T_(A)M_(B)=T_(B)M_(A) , then which property has the same magnitude for both the gases?

There are two thin spheres A and B of the same material and same thickness. They behave like black bodies, Radius of A is double that of B and Both have same temperature T. When A and B are kept in a room of temperature T_0 (lt T) , the ratio of their rates of cooling is (assume negligible heat exchange between A and B).

Three Carnot engines operate in series between a heat source at a temperature T_(1) and a heat sink at temperature T_(4) (see figure). There are two other reservoirs at temperature T_(2) and T_(3) , as shown, with T_(1)gtT_(2)gtT_(3)gtT_(4) . The three engines are equally efficient if :

In the following P-V diagram two adiabatics cut two isothermals at temperature T_(1) and T_(2) (fig). The value of V_(a)/V_(d) will be
