Q. while a system is taken from state a to state b in the figure below the path acb, 84.0 of heat flows into the system and 57.0 of work is done by the system.

A. How much heat flows into the system along path adb if the work completed by the system is 15?

B. When the system is returned from b to a along the curved path, absolute value of the work done by the system is 34.00. How much heat does the system liberate?
