AP Physics 2
9.1 Kinetic Theory of Temperature and Pressure
Four separate rigid containers each hold a dilute sample of an ideal gas. The molecular mass and absolute temperature of the gas in each container are given in the table.
Which of the following correctly ranks the root-mean-square speed \(v_{\text{rms}}\) of the gas molecules in the four containers?
| Container | Molecular Mass | Absolute Temperature |
|---|---|---|
| 1 | \(m_0\) | \(2T_0\) |
| 2 | \(m_0\) | \(T_0\) |
| 3 | \(4m_0\) | \(4T_0\) |
| 4 | \(4m_0\) | \(T_0\) |
Which of the following correctly ranks the root-mean-square speed \(v_{\text{rms}}\) of the gas molecules in the four containers?
