Final answer:
Oxygen exhibits its highest velocity at extremely high temperatures.
Step-by-step explanation:
At extremely high temperatures, oxygen exhibits its highest velocity. Oxygen exhibits its highest velocity at extremely high temperatures. The most probable speed, average speed, and root mean square speed of oxygen molecules depend on the temperature.
In Figure 9.32, the molecular speed distribution for oxygen gas at 300 K is shown, with the most probable speed, vp, being a little less than 400 m/s and the root mean square speed, Urms, being closer to 500 m/s. Therefore, at temperatures exceeding 300 K, the velocity of oxygen molecules would be higher.
