Question

The particles of a solid diffuses with a liquid.... diffusion, acc 2 book means, the movment of the particles on their own... then u dont the particles of the solid diffuse with air????? i jst cant get y.. plzz help!!! and one more... wht is the difference betwn brownian motion and diffusion??

Answer 1

The Brownian motion has the same nature as diffusion, yet it is much slower due to large size and
mass of particles. The particles of a solid can diffuse in air as well as in liquid; however, the larger density of solid particles as compared with gas will cause their subsidence. Therefore, their air suspension will be unstable.
