Question:medium
A gas can be taken from A to B via two different processes ACB and ADB. When path ACB is used, \( 60 J \) of heat flows into the system and \( 30 J \) of work is done by the system. If path ADB is used, the work done by the system is \( 10 J \). The heat flow into the system in path ADB is:

Show Hint
Change in internal energy \( \Delta U \) depends only on initial and final states, not on the path.
