JEE Main 2024Kinetic Theory of Gases Question with Solution

JEE Main 2024 (30 Jan Shift 1)

Question

Two thermodynamical process are shown in the figure. The molar heat capacity for process A and B are CA and CB. The molar heat capacity at constant pressure and constant volume are represented by CP and CV, respectively. Choose the correct statement.

Show full solutionCorrect option: A
Correct answer
ACP>CB>CV

Step-by-step explanation

For process A:

logP=γlogVP=Vγ,(γ>1)

PV-γ= Constant

CA=CV+R1+γ i

Likewise, for process BPV-1= Constant

CB=Cv+R1+1

CB=Cv+R2 ii

Also, CP=Cv+R iii

By ii and iii, we get

CP>CB>Cv
