What is the de-Broglie wavelengths of a nitrogen molecule in air at 300 K? Assume that the molecule is moving with the root-mean-square speed of molecules at this temperature. (Atomic mass of nitrogen = 14.0076 u).

What is the de-Broglie wavelength of an atom of mass m, moving at absolute temperature T K?

What is the de-Broglie wavelength of a ball of mass 0.060 kg moving at a speed of 1.0 m/s.

The root mean square and most probable speed of the molecules in a gas are:

How do you distinguish between average speed and root mean square speed of the molecules of a gas?

Estimate the mean free path and collision frequency of a nitrogen molecule in a cylinder containing nitrogen at 2.0 atm and temperature 17 ^@C . Take the radius of a nitrogen molecule to be roughly 1.0overset@ A . Compare the collision time with the time the molecule moves freely between two successive collisions (Molecular mass of N_2 = 28.0 u).

Three vessels of equal capacity have gases at the same temperature and pressure. The first vessel contains neon (monatomic), the second contains chlorine (diatomic), and the third contains uranium hexafluoride (polyatomic). Do the vessels contain equal number of respective molecules ? Is the root mean square speed of molecules the same in the three cases? If not, in which case is u_rms the largest ?

At what temperature, the molecules of nitrogen will yhave the same rms velocity as the molecules of oxygen at 127^@ C ?

Two molecules of a gas have speeds of 9 xx 10^6 rms^-1 and 1 xx 10^6 ms^-1 , respectively. What is the root mean square speed of these molecules?

The rms speed of N_(2) molecules in a gas in u . If the temperature is doubled and the nitrogen molecules dissociate into nitrogen atom, the rms speed becomes
