# 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 \(P_{\text{sensor}}\)

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 \(P_{\text{sensor}}\)

![A Cartesian graph plotting measured pressure P_sensor in kilopascals (kPa) on the vertical axis against temperature T in degrees Celsius (°C) on the horizontal axis. The vertical axis ranges from 0 to 600 kPa with tick marks every 100 kPa. The horizontal axis ranges from 0 to 140 °C with tick marks every 20 °C. A solid linear best-fit line passes through two clearly highlighted data points: a point at (20, 330) labeled (20 °C, 330 kPa) and a point at (120, 480) labeled (120 °C, 480 kPa). The line extends smoothly through both points across the entire grid with a constant positive slope. No other labels, lines, text, or axes appear.](https://nerd-notes.com/wp-content/uploads/ubq-frq-generated/stem-fig-1-1785826335-wSOYXc.jpg)
