Figure below shows two paths that may be taken by a gas to go from a state A to a state C.
In process AB, 400 J of heat is added to the system and in process BC, 100 J of heat is added to the system. The heat absorbed by the system in the process AC will be :
Answer & explanation
Correct answer: option 2
\(\Delta U_{cyc} = 0\)
Qcyc = Wcyc
QAB + QBC + QCA = closed loop area
400 + 100 + QCA = 1/2 x 2 x 10-3 x 4 x 104
QCA = 460 J
