A system goes from A to B via two processes I and II as shown in figure. If Δ U1and Δ U2 are the changes in internal energies in the processes I and II respectively, then Question

(A) Δ U1= Δ U2 (B) Relation between Δ U1and Δ U2 cannot be determined (C) Δ U2> Δ U1 (D) Δ U2 < Δ U1

The change in internal energy does not depend upon path followed by the process. It only depends on initial and final states. Hence, Δ U1=Δ U2

Q. A system goes from A to B via two processes I and II as shown in figure. If $Δ U_{1} an d Δ U_{2}$ are the changes in internal energies in the processes I and II respectively, then

$Δ U_{1} = Δ U_{2}$

Relation between $Δ U_{1} an d Δ U_{2}$ cannot be determined

$Δ U_{2} > Δ U_{1}$

$Δ U_{2} < Δ U_{1}$

The change in internal energy does not depend upon path followed by the process. It only depends on initial and final states.
Hence, $Δ U_{1} = Δ U_{2}$

Q. A system goes from A to B via two processes I and II as shown in figure. If ΔU1​andΔU2​ are the changes in internal energies in the processes I and II respectively, then

ΔU1​=ΔU2​

Relation between ΔU1​andΔU2​ cannot be determined

ΔU2​>ΔU1​

ΔU2​<ΔU1​
