The direction of their motion changes randomly.
Random
Heat motion is random.
circular motion linear motion random motion
Brownian motion
They move in a straight line until they hit something and bounce off. Molecules in a gas show random rectilinear motion. This is called Brownian motion
Brownian motion is the random moving and mixing of particles.

Brownian motion is the random moving and mixing of particles.
Heat motion is random.
Molecules, atoms, ions, or other small particles of whatever sort are moving all the time; there is random thermal motion even when these particles are part of a larger object which is not moving. These moving particles are constantly bouncing off each other, in perfectly elastic collisions in which no energy is lost, so they just keep moving. The result of this random motion is that a concentration of a substance will gradually spread out, unless it is contained in some manner. In summery random motion of a substance resulting in movement from area of high to lower concentration.
Diffusion- the random motion of gases moving from a higher concentration to a lower concentration.
Heat is random motion or vibrations that take place on an atomic or molecular level. The faster particles are moving, the hotter they are.
sugar molecules are widely spreaded and are moving at random motion
