When a system is taken through the process abc shown in figure, 80 J of heat is absorbed by the system and 30 J of work is done by it. If the system does 10 J of work during the process adc, how much heat flows into it during the process ?

Q. When a system is taken from state $A$ to state $B$ along the path $ACB,80J$ of heat flows into the system and the system does $30J$ of work. (a) How much heat flows into the system along path $ADB$ if the work done ins $10J$? (b) When the system is returned from the state $B$ to $A$ along the curved path, the work done on the system is $20J$. Does the system absorb or liberate heat, and how much? (c) If $U_D-U_A=40J$, find the heat absorbed in the process $AD$ and $DB$.

Q. When a system is taken from A to C through path ABC, 10 J of heat flows to the system and 4 J of work is done by the system.How much heat flows into the system in path ADC, if the work done by the system is 3 J?
