A system is allowed to move from state $A$ to $B$ following path $\mathrm{ACB}$ by absorbing $80 \mathrm{~J}$ of heat energy. The work done by the system is $30 \mathrm{~J}$. The work done by the system in reaching state $B$ from $A$ is $10 J$ through path ADB. Which statements are correct?
I. Increase in internal energy from state $A$ to state $B$ is $50 \mathrm{~J}$.
II. If path $\mathrm{ADB}$ is followed to reach state $\mathrm{B}$
$\Delta \mathbf{E}=50 \mathrm{~J}$.
III. If work done by the system in path $A B$ is $20 \mathrm{~J}$, the heat absorbed during path $\mathrm{AB}=70 \mathrm{~J}$
IV. The value $\mathrm{E}_C-\mathrm{E}_{\mathrm{A}}$ is equal to $\mathrm{E}_{\mathrm{D}}-\mathrm{E}_{\mathrm{B}}$.
V. Heat absorbed by the system to reach $B$ from $A$ through path $A D B$ is $60 \mathrm{~J}$.
