Molecular-kinetic theory is called teaching, which explains the structure and properties of matter by the motion and interaction of particles, of which the substance consists.
The atom is the smallest particle of a given chemical element.
A molecule is the smallest stable particle of a given substance that has its basic chemical properties. A molecule consists of one or several atoms of the same or different chemical elements.
The quantity of a substance is a physical quantity determined by the number of specific structural elements of molecules, atoms or ions.
Permanent Avogadro is the number of atoms (molecules or other structural elements) contained in one mole of matter.
Brownian motion is the continuous chaotic motion of particles placed in a liquid or gas under conditions such that gravity does not affect their motion (suspended particles).
Diffusion in the simplest case is the process of equalizing the densities (or concentrations) of two substances when they are mixed with each other.
Solid are called bodies, which differ in the constancy of form and volume.
Crystals are solids having an ordered, periodically repeating in space arrangement of their particles.
Single crystals are single crystals that have the shape of regular polyhedra.Fluids are bodies that have a certain volume, but do not have their shape, taking the form of the vessel in which they are located.
An ideal gas is a gas, between the particles of which there are no forces of mutual attraction.
The mean time T of the mean free path of a particle is the time during which the particle moves without collisions, i.e. this is the average time between two consecutive collisions:
Thermodynamics is the division of physics, in which the conditions for the transformation of energy from one type into another and the quantitative relationships under such transformations are studied.
