HI


I THINK DA ANSWER 2 DIS QUESTION IZ [A]4R/2


DIS IZ AN ISOTROPIC PROCESS (defiined as process in which PV*=constant hereV*meansV ki power x)AND FORMULA OF MOLAR HEAT CAPACITY FOR SUCH A PROCESS IZ=R/y-1-R/x-1 y=5/3 for a monoatomic ideal gas and here P/V=CONSTANT SO x=-1 so ANSWER=3R/2-(-R/2)=4R/2. U CAN FIND DERIVATION OF DIS FORMULA IN HCV . PLZ REPLY ME IF D ANSWER IS CORRECT OR NOT.
