When a system is taken from
state A to state B along path \( \mathrm{ACB} \) as shown in figure below, \( 80 \mathrm{~J} \)
of heat flows into the system and the system does \( 30 \mathrm{~J} \) of work.
When the system is returned from state B to A along the curved path, the work done on the system is \( 20 \mathrm{~J} \). Does the system absorb or liberate heat and by how much ?
(a) \( -70 \mathrm{~J} \); heat is liberated
(b) \( -60 \mathrm{~J} \); heat is liberated
(c) \( +70 \mathrm{~J} \); heat is absorbed
(d) \( +60 \mathrm{~J} \); heat is absorbed.
