A rigid container with a fixed volume of \(V = 8.31 \times 10^{-3}\text{ m}^3\) contains a sample of an ideal gas. The pressure of the gas is measured using a sensor that has an unknown, constant offset error \(P_0\), such that \(P_{\text{sensor}} = P_{\text{gas}} + P_0\). The graph shows the measured pressure \(P_{\text{sensor}}\)
