When a system is taken from
state A to state B along path ACB as shown in figure below, \( 80 \mathrm{~J} \)
of heat flows into the system and the system does \( 30 \mathrm{~J} \) of work.
If \( \mathrm{E}_{\mathrm{D}}-\mathrm{E}_{\mathrm{A}}=-40 \mathrm{~J} \), the heat absorbed in the processes \( \mathrm{AD} \) and \( \mathrm{DB} \) are respectively : (work done by the system in process \( \mathrm{AD} \) is \( 10 \mathrm{~J} \) )
(a) \( \mathrm{q}_{\mathrm{AD}}=30 \mathrm{~J} \) and \( \mathrm{q}_{\mathrm{DB}}=-90 \mathrm{~J} \)
(b) \( \mathrm{q}_{\mathrm{AD}}=-60 \mathrm{~J} \) and \( \mathrm{q}_{\mathrm{DB}}=30 \mathrm{~J} \)
(c) \( \mathrm{q}_{\mathrm{AD}}=30 \mathrm{~J} \) and \( \mathrm{q}_{\mathrm{DB}}=90 \mathrm{~J} \)
(d) \( \mathrm{q}_{\mathrm{AD}}=-30 \mathrm{~J} \) and \( \mathrm{q}_{\mathrm{DB}}=90 \mathrm{~J} \)
