Determine the collision frequency and mean free path for

Question

Find the temperature T at which V_mp = c (the velocity of light) for the neon atoms discussed in Examples 1 and 2.

Example 1:

Determine the collision frequency and mean free path for neon at 273 K and 0.113 MPa. The molecular mass of neon is 20.183 kg/kgmole.

Example 2:

Test assumption 7 at the beginning of this section by computing the fraction of neon molecules at 273 K whose velocities are faster than (a) V_mp, (b) V_avg, (c) V_rms, and (d) c (the speed of light). Use the molecular data for neon given in Example 1.
