Introduction to Chemical Engineering Thermodynamics

When a system is taken from state a to state b in the accompanying 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 alongpath bda. If the work done on the system is 30 J, does the system absorb or liberate heat? How much?
