When a system in a given initial state
goes through a number of different changes in state (goingthrough various processes)
and finally returns to its initial values, the system has
undergone acyclic
process or cycle. Therefore, at the conclusion of a
cycle, all the properties have the samevalue
they had at the beginning. Steam (water) that circulates
through a closed cooling loopundergoes
a cycle.
