    Brownian motion is the random movement of colloidal particles suspended in a fluid. It is caused by random collisions of the molecules in the fluid medium. The particles in the solution or colloids are in constant random movement. A colloid has properties boundary to a homogenous and heterogeneous mixture. However in Brownian movement, the larger the size of a particle, the lesser its motion and the smaller the size of the particle, the higher is motion. Colloids in general have larger particle size and therefore it Brownian motion is sluggish. The statement is false.
