  • For Brownian motion of particle, match column I and II.                Factor                 

For Brownian motion of particle, match column I and II.

               Factor                                                                    Effect

     (i) Decrease in size of Brownian particle            (P) Increase of Brownian motion

      (ii) Decrease in density of medium                    (Q) Decrease of Brownian motion

       (iii) Increase in temperature of medium             (R) Unaffected

       (iv) Increase in viscosity of medium  

Option: 1

[(i) - P], [(ii)-P], [(iii)-P], [(iv)-R]


Option: 2

[(i) - P], [(ii)-Q], [(iii)-R], [(iv)-P]


Option: 3

[(i) - P], [(ii)-P], [(iii)-P], [(iv)-Q]


Option: 4

[(i) - R], [(ii)-P], [(iii)-P], [(iv)-Q]

As we learn

Brownian Motion -

The continuous random motion of the partilce of microscopic size suspended in air or liquid.

- wherein

By decreasing size of molecule, the space for random motion is increased so the Brownian motion increases

By decreasing the density the space for random motion is increased so the Brownian motion increases

By increasing temperature, the energy of each particle again increases, So the Brownian motion increases

If vicosity increases, then the friction between the molecules increases and the motion of molecule face difficulty and Brownian motion decreases.
