Question
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
-
380 J
-
500 J
-
460 J
-
300 J
Solution
C.
460 J
Since, initial and final points are same
