    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.
