Three different processes that can occur in an ideal monoatomic gas are shown in the $P$ vs $V$ diagram. The paths are labelled as $A \rightarrow B, A \rightarrow C$ and $A \rightarrow D .$ The change in internal energies during these process are taken as $E _{ AB }, E _{ AC }$ and $E _{ AD }$ and the work done as $W _{ AB }$ $W _{ AC }$ and $W _{ AD }$

The correct relation between these parameters are

  • A$E _{ AB }= E _{ AC }= E _{ AD }, W _{ AB }>0, W _{ AC }=0,$ $W _{ AD }>0$
  • B$E _{ AB }< E _{ AC }< E _{ AD }, W _{ AB }>0, W _{ AC }> W _{ AD }$
  • C$E _{ AB }= E _{ AC }< E _{ AD }, W _{ AB }>0, W _{ AC }=0$ $W _{ AD }<0$
  • D$E _{ AB }> E _{ AC }> E _{ AD }, W _{ AB }< W _{ AC }< W _{ AD }$

    A closed container contains a homogeneous mixture of two moles of an ideal monatomic gas $(\gamma=5 / 3)$ and one mole of an ideal diatomic gas $(\gamma=7 / 5)$. Here, $\gamma$ is the ratio of the specific heats at constant pressure and constant volume of an ideal gas. The gas mixture does a work of $66$ Joule when heated at constant pressure. The change in its internal energy is. . . . . . .Joule.
