A system goes from A to B via two processes 1 and 11 as shown in figure. If Δ U1 and Δ U2 are the changes in internal energies in the processes I and II respectively, then : (A) Δ U1=Δ U2 (B) relation between Δ U1 and 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 $1$ and $11$ as shown in figure. If $Δ U_{1}$ and $Δ U_{2}$ are the changes in internal energies in the processes I and II respectively, then :

$Δ U_{1} = Δ U_{2}$

relation between $Δ U_{1}$ and $Δ U_{2}$ 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 1 and 11 as shown in figure. If ΔU1​ and ΔU2​ are the changes in internal energies in the processes I and II respectively, then :

ΔU1​=ΔU2​

relation between ΔU1​ and ΔU2​ cannot be determined

ΔU2​>ΔU1​

ΔU2​<ΔU1​
