Question

calculate the root mean square velocity and average velocity of nitrogen gas at NTP ?​

Answer 1

Answer:

The Root Mean Square velocity of Nitrogen molecules at N.T.P. is 493 m/s.

Nitrogen molecule is 28 neuclons×1.67×10-27 kg/neucleon = 4.68 д 10-26 kg. So the average speed of a gas molecule is about 500 m/sec. This is roughly the speed of sound in a gas 340 m/sec. So the average kinetic energy of the gas molecules is related to the temperature of the gas.
