Explain the cause of Brownian motion
Briefly define or explain the cause of Brownian motion?
Expert
Molecules in the gas move constantly, freely, arbitrarily, in all the directions and at high speeds. They are capable to do so as the intermolecular force of attraction among the molecules is negligible whenever in a gaseous state. This constant motion of molecules causes them to collide with everything in their path. For illustration, the dust particles will be bombarded through the molecules moving at high speeds, causing them to encompass a zigzag motion.
Brownian motion as well occurs in molecules in a liquid, however to a less obvious extent than in the gas.
Hooke's law (R. Hooke): The stress exerted to any solid is proportional to the strain it generates within the elastic limit for that solid. The constant of that proportionality is the Young modulus of elasticity for that material.
Reflection law: For a wave-front intersecting a reflecting surface, the angle of incidence is equivalent to the angle of reflection, in the similar plane stated by the ray of incidence and the normal.

Pauli Exclusion Principle (W. Pauli; 1925): No two similar fermions in a system, like electrons in an atom, can contain an identical set of the quantum numbers.
Kirchhoff's laws (G.R. Kirchhoff) Kirchhoff's first laws: An incandescent solid or gas in high pressure will generate a continuous spectrum. Q : Polarization In a non-polar - molecule, In a non-polar - molecule, the centre of the nuclei and electron orbit overlap when such a molecule is positioned in electric field, the electrons are attracted with the positive charged of the anode and repelled by the negative charges of the cathode. Because of grea

Speed of light (in vacuo): c: The speed at which the electromagnetic radiation spreads in a vacuum; it is stated as 299 792 458 m/s.
