Q: In a closed system with constant temperature, pressure can be plotted against volume in a PV diagram. Given this, which of the following is NOT true?
A		The amount of energy expended by the system can be estimated by an area on the graph.
B		The relationship between pressure and volume would always be linearly decreasing.
C		The change in internal energy is equal to 0.
D		An appropriate example that can be plotted in this PV diagram is an ideal gas in a container (in a constant-temperature environment) which is allowed to expand slowly.
