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.

Actually in the first page the formulae are deduced by using calorimetric principle.Which can be used for solid and liquid. But for the case of gas a slide increase in temparature can cause huge change in pressure and volume.You have to take count all of those. In the problem of second page two ideal gases are mixed.So here you cannot use the calorimetric principle here.Here you have to solve the problem as given.

first remember that extensive property is additive ,example volume, Internal energy, no of moles, specific heat. these formulas are derived from here only.. here in the ques we don't use the formulas of first page because in the question we have two different gas one is monoatomic and other is diatomic, both have different Cv, but in the formulas that is in first page has same value of C .. so don't get confuse.. use these formulas that I attached , u will get ur ans in every ques using these.. best regards
