A gas can be taken from A to B via two different processes ACB and ADB. When path ACB is used 60, J of heat

Q: A gas can be taken from $A$ to $B$ via two different processes $ACB$ and $ADB$. When path $ACB$ is used $60\, J$ of heat flows into the system and $30\, J$ of work is done by the system. If path $ADB$ is used work down by the system is $10\, J$. the heat flow into the system in path $ADB$ is ..... $J$

a As temperature at point $A$ and $C$ is same. $\therefore$ Internal energy change will be same. $\mathrm{Q}-\mathrm{W}=\mathrm{Q}^{\prime}-\mathrm{W}^{\prime}$ $60-30=Q^{\prime}-10$ $Q^{\prime}=40 \mathrm{J}$
