Question
When a system is taken from state a to state b in the diagram below along the
path acb, 90.0 J of heat go into the system and 60.0 J of work is done by the
system.
a) How much heat is transferred into the system along path adb if the work done
by the system is 15.0 J?
b) When the system is returned from b to a along the curved path, the absolute
value of the work done by the system is 35.0 J. Does the system absorb or
liberate heat? How much heat?
c) If U. = 0 J and Ua= 8.0 J, find the heat absorbed in the processes ad and db.
