- Summary
- In fluids, microscopic particles move in a random and irregular manner due to the constant agitation of the atoms and molecules which make up the surrounding medium. The hotter the medium is the faster the particles move. Each collision with the surrounding medium causes the particles to accelerate. Between two collisions, their movement is straight and at a steady speed.
