NEET Physics Thermodynamics Questions Solved

A system goes from A to B via two processes I and II as shown in figure. If ΔUI and ΔUII are the changes in internal energies in the processes I and II respectively, then 

(1) ΔUII > ΔUI

(2) ΔUII < ΔUI

(3) ΔUI = ΔUII

(4) Relation between ΔUI and ΔUII can not be determined

(3) As internal energy is a state function therefore change in internal energy does not depends upon the path followed i.e. ΔUI=ΔUII
