On a PV Diagram,2 Curves Are Plotted,both Starting at the Same

Multiple Choice

On a PV diagram,2 curves are plotted,both starting at the same point and both ending at the same final increased volume.One curve is for an isothermal process;the other is for an adiabatic process.What does the area between these two curves represent?

A) Q absorbed by the isothermal process.
B) W done by the adiabatic process.
C) ΔU for the isothermal process.
D) Neither Q,W,nor ΔU for either of the processes is represented.
