(a) When a system is taken from state C to state A along the direct curved path CA, 30 J of heat flows into the system and the system does 25 J worth of work. What is AU for this process? (note: CA is not an isotherm) (b) When the system goes from C to A via the path CBA, the work done by the system is 20 J. i. What is AU for this process (going from C to A along CBA)? ii. Does the system absorb or liberate heat? How much?
