A Cyclic Process Is Carried Out on an Ideal Gas

A cyclic process is carried out on an ideal gas such that it returns to its initial state at the end of a cycle.

If the process was carried out in a counter-clockwise sense around the enclosed area, as shown on the p-V diagram in Figure 12-5, then that area represents

A) the work done on the ideal gas.
B) the heat added to the ideal gas.
C) the work done by the ideal gas.
D) the heat that flows from the ideal gas.
