At what temperature is the average speed of air particles the highest?


Sagot :

Answer:

Explanation:

Air is a mixture of roughly 80% nitrogen and 20% oxygen. The diatomic molecules of each type have a Maxwell-Boltzman distribution of velocities.

From the kinetic theory of gases the molecules kinetic energy will depend on the temperature.

Let’s use 300 K as room temperature : The nitrogen molecules have a root mean square velocity ( VRMS ) of 353 m/s. The average for all of the molecules is 347 m/s.

In general in gases of diatomic molecules the speed of sound is 68% of the molecular  VRMS .
