Question

Which is the major problem while trying to observe Brownian Motion?

Answer 1

Answer:

Explanation:

" the ceaseless, erratic, zig-zag motion exhibited by colloidal particles is called Brownian motion"

• it is due to unequal bombardment of colloidal particle by constantly moving molecules dispersion medium.
• Brownian motion of of sol particles is slower than the molecular motion because colloidal particles are heavier than molecules
• since brownian motion counteracts the force of gravity acting on the colloidal particles, it is responsible to some extent for the stability of colloidal solutions
