Question

which of these show brownium motion​

Answer 1

$\huge\mathrm\pink{\underline{Answer:}}$

The phenomenon of Brownian motion was observed by Robert Brown in the form of random zig-zag motion of pollen grains suspended in water. This kind of movement is found in all colloidal systems. Such random motion is visible under ultramicroscopes and for bigger particles even under ordinary microscopes.
