Exercise Problem
When a close system is taken from state a to state b shown in
Figure along path acb, 100 J of heat flows into the system and the
system does 40 J of work.
a) How much heat flows into the system along path aeb if the work
done by the system is 20 J?
b) The system returns from b to a along path bda. If the work done
on the system is 30 J, does the system absorb or liberate heat?
How much?
