AP Physics 2
9.4 The First Law of Thermodynamics
BeginnerMCQConceptual23k
A thermodynamic PV graph with pressure P on the vertical axis and volume V on the horizontal axis. A point labeled state 1 is positioned at coordinates (V_0, P_0). A second point labeled state 2 is positioned directly above state 1 at coordinates (V_0, 2P_0). A solid vertical line with an upward-pointing arrowhead connects state 1 to state 2. The area under the vertical line is zero. No other labels, lines, text, or axes appear.
Pressure versus volume for the gas.
A fixed amount of ideal gas is sealed inside a rigid container with a constant volume \(V_0\). Heat is added to the gas, causing its pressure to increase from \(P_0\) to \(2P_0\), as shown in the pressure \(P\) versus volume \(V\) diagram. Which of the following claims correctly describes the work done on the gas during this process, and what justification supports this claim?
