In physics, can it be said that the Brang motion is the motion of the molecules why?

No, the Blang motion is when the molecules hit the particles, and the particles move only when they are impacted, and the particles are passively moving.

The Bronch motion is just proof that the molecules are in motion.

The phenomenon of suspended particles moving irregularly was discovered in 1827 by the British botanist Brown (1773-1858) who used a microscope to observe pollen suspended in water. Later, this motion of suspended particles was called Brownian motion. Brownian motion can be observed not only in pollen and small charcoal particles, but also in a variety of different suspended particles in liquids.

So, how did Brownian motion come about? What appears to be a liquid under a microscope is actually made up of many molecules. The liquid molecules are constantly moving in an irregular motion, constantly grasping at the senior particles.

The suspended particles are small enough to be hit by liquid molecules from all directions in an unbalanced manner. At one point, the impact of the particle in the other direction is strong, causing the particle to move in the other direction. In this way, the irregular Brownian motion of the particles is caused.

In 1827, the Scottish botanist R. Brown discovered that pollen and other tiny particles suspended in water were constantly moving in irregular polygonal lines, called Brownian motion. People didn't know how it works for a long time.

Fifty years later, J. Deerso proposed that these tiny particles are caused by the unbalanced collision of surrounding molecules. It was later proved by Einstein's research.

Brownian motion thus became the basis for the development of molecular kinematics and statistical mechanics.

Both colloids and pollen do Brownian motion.

Not exactly, Brownian motion refers to the never-ending, irregular motion of particles suspended in a liquid or gas. It got its name from the discovery by the English botanist Brown.

The diameter of the particles of Brownian motion is generally 10-5 10-3 cm, when these small particles are in a liquid or gas, due to the thermal motion of liquid molecules, the particles are collided with liquid molecules from all directions, and when they are hit by an unbalanced impact, they move, because of this unbalanced collision, the movement of the particles constantly changes direction and makes the particles appear irregular motion.

Each small particle in the liquid is collided with by the surrounding liquid molecules at a frequency of about 102 times per second. The intensity of Brownian motion increases as the temperature of the fluid increases.

The correct statement is that Brownian motion refers to the irregular movement (observed under a microscope) of tiny pollen particles suspended on the surface of a liquid, which is caused by the irregular movement of liquid molecules.

Brownian motion is the irregular motion of suspended particles in a liquid due to the irregular impact of the liquid molecules.

Brownian motion is the irregular motion of liquid molecules, not the irregular motion of liquid molecules.

Liquid molecules move irregularly, and suspended particles move irregularly, but Brownian motion refers to the motion of suspended particles.

Right; Brownian motion is a liquid that is made up of many molecules under a high-powered microscope. The liquid molecules are constantly moving in an irregular motion, constantly hitting the suspended particles at random. When the suspended particles are small enough, they are unbalanced due to the impact of liquid molecules from all directions.

At a certain moment, when the impact of the particle in the other direction is super strong, the particle moves in other directions, so that the irregular motion of the particle is Brownian motion.

Brownian motion indirectly illustrates the never-ending irregular motion of molecules.

The cause of Brownian motion: suspended particles (about mm in diameter, called "Brownian particles") surrounded by liquid molecules or gas molecules, which are unbalanced by the impact of liquid or gas molecules from all directions at any time, and the particles move in the direction of the stronger impact, so that the particles have irregular motion. It should be noted that the Brownian front motion is not a molecular movement, but a manifestation of molecular movement.

Factors influencing the apparentness of Brownian motion: the smaller the solid particle, the smaller the number of liquid molecules striking it, and the more obvious this imbalance is; The smaller the solid particle, the smaller the mass, and the state of motion is easy to change, so the smaller the solid particle, the more significant the Brownian motion. The higher the temperature of the liquid, the more intense the Brownian motion becomes.

Brownian motion and molecular thermal motion are not the same thing.

As long as there is a temperature object, the molecules inside it will not be stationary, but will never stop irregular motion, we call the motion of the molecules inside the object itself molecular thermal motion. But the movement itself cannot be seen with the naked eye.

It was found that the pollen particles are put into the liquid, and the pollen particles can be seen from the microscope to do irregular motion, in fact, it is not that the pollen particles themselves have the power to move, but the liquid molecules around it are doing molecular thermal motion, and the thermal movement is irregular, and the speed of each molecule is different, so under the impact of these liquid molecules, the pollen particles are forced to make irregular movements, which we call Brownian motion.

Hello, now I am here to answer the above questions for you. Brownian motion is not a molecule doing irregular motion, Brownian motion is not a hot motion defeat seepage letter demolition boring many friends still don't know, now let's take a look at the bend. <>

Hello, now I am here to answer the above questions for you. Whether Brownian motion is a molecular irregular motion, whether Brownian motion is a hot motion I believe many friends still don't know, now let's take a look!

1. Brownian motion is the phenomenon of suspended particles moving irregularly without stopping.

2. Molecular thermal motion does not belong to Brownian motion because molecules suspend particles.

3. Brownian motion refers to the irregular motion of small particles due to the impact of the irregular thermal motion of molecules under the influence of molecular thermal motion.
