Question

what is the meaning of brawhiam motion​

Answer 1

Answer:

I think you mean the definition of 'Brownian Motion'.

Explanation:

Brownian Motion refers to the random and erratic motion of particles in a fluid ( gas or liquid) which is the result of continuous bombardment/collisions of the fluid molecules against the particle. This was first observed by Robert Brown, a botanist who saw this weird random motion and theorized the concept of individual molecules of a fluid moving independently. Albert Einstein published a paper proving this theoretically and a man named Jean Perrin proved this experimentally in 1908. Later, Jean Perrin was awarded the Nobel Prize for this.
