A system goes from A to B via two processes I and II as shown in the figure. IfDeltaU_(1)and DeltaU_(2)are the changes in the internal energies in the processes I and II respectively, then -

Answer»

`DeltaU_(1)=DeltaU_(2)`
relation between `DeltaU_(1) and DeltaU_(2)`cannot be determined
`DeltaU_(2) gt DeltaU_(1)`
`DeltaU_(2) LT DeltaU_(1)`

Solution :
`:' (DELTAU)_(I)=(DeltaU)_(II)`
& [depends only on path not upon initial and final state]
