1.	A system goes from A and B via two processes. I and II as shown in figure. If `DeltaU_1 and DeltaU_2` are the changes in internal energies in the processes I and II respectively, then
Answer» As initial and final states A and B for the two processes are the same for two processes and change in internal energy is independent of the path, `:. dU_(1)=dU_(2)`
