Does tint in a water glass move randomly?

346 viewsOtherPhysics

If we let a tint drop fall into a glass of water, it looks like it spreads randomly.

But let’s they we could repeat the experiment under the exact same conditions (with the same glass, water volume, arrangement of water molecules, amount of tint, fall height and everything that could affect the equation). Would the tint drop spread exactly the same or would it still be random? Do we have any knowledge about the correlation of time and matter in an theoretical experiment like this?

Brownian motion…

It is the seemingly random movement of microscopic particles suspended in a fluid (liquid or gas). This erratic movement is caused by the constant bombardment of the particles by the surrounding fluid molecules, which are themselves constantly moving due to their thermal energy. The smaller the particle, the more noticeable the Brownian motion.
