Question

Consult Interactive Solution 14.33 to see how this problem can be solved. Very fine smoke particles are suspended in air. The translational rms speed of a smoke particle is 3.8 x 10^-3 m/s, and the temperature is 301 K. Find the mass of a particle. (Answer must be in kg). Thanks.

Answer 1

Ans:

Explanation:

Given:

rms speed of smoke particle ,

Temperature of gas , T = 301 K

Let the mass of air particle is m.

We know , the rms speed of the particle is given by

where = Boltzmann constant.

So mass of particle is
