The image depicts a Pressure-Volume (P-V) diagram illustrating a thermodynamic process involving a gas. The graph has the pressure (P) on the vertical axis and the volume (V) on the horizontal axis. ### Description of the Graph: - **Points 1, 2, 3**: These represent different states of the gas during the process. - **State 1**: - Temperature (\(T_1\)) = 300 K - Pressure is 1.00 atm (indicated on the vertical axis). - **State 2**: - Temperature (\(T_2\)) = 600 K - The system moves from state 1 to state 2 along a vertical path, indicating a change at constant volume. - **State 3**: - Temperature (\(T_3\)) = 492 K - The transition from state 2 to state 3 occurs along a curve, showing a change in both pressure and volume. ### Pathway: - The arrows indicate the direction of the process, moving sequentially from state 1 to state 2 and then to state 3. - The transition from state 1 to state 2 is vertical, representing an isochoric (constant volume) process where only pressure changes. - The curve from state 2 to state 3 suggests a combined variation in both pressure and volume, typically indicative of an adiabatic or polytropic process. This diagram is useful for understanding thermodynamic cycles and transformations, illustrating how the state of a gas changes in a controlled manner under different conditions.
