Heat motion is random.
Electrons are the particles that move around the nucleus in constant and random motion.
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.
Heat is random motion or vibrations that take place on an atomic or molecular level. The faster particles are moving, the hotter they are.
Random motion is a property of all particles. Brownian motion, the random redistribution of particles due to individual random motion, is possible in fluids, including gasses, liquids, and plasmas, but not in solids- the structure of solids prevents individual particles from moving out of place until they gain enough energy for their small random movements to break free. The key feature of gasses relating to motion is that the particles have an appreciable amount of space between them and can travel many times farther before encountering another gas particle than is possible in a liquid. This allows the rapid diffusion of different gasses into a homogeneous mixture.
are in random, constant, straight-line motion
if this is about the motion of the particles,it is brownian motion.the random motion of the particles.
That is called Brownian motion.
Brownian motion. This is random motion of micro particles resultimg from collisions between the particle in question and other particles in the surrounding medium.
