What Is Brownian Movement?

Answer Question

1 Answer - Sort by: Date | Rating

    Brownian Movement or Motion is the irregular zigzag movement of tiny particles when they are suspended in fluid. Brownian Movement is named after Robert Brown, a botanist who observed the irregular movement of plant spores in water. This effect is observable in all kinds of solutions, whether solid-in-liquid, liquid-in-liquid, liquid-in-gas,gas-in-liquid, and solid-in-gas. It does not involve larger objects such as bricks and such but particles which are not more than 0.001 mm in diameter. The effect occurs as a result of the thermal motion of the fluid molecules. When tiny particles are suspended in the fluid, they are buffeted by the fluid molecules. Although, first observed by Robert Brown, Albert Einstein was the first to give a credible theoretical explanation of Brownian Movement, in  1905.
