Definition of Schrödinger equation

Schrödinger's equation is the name given to a key foundation for quantum mechanics with a non-relativistic approach that, at first, was considered as a simple equation of motion based on a material field whose propagation had a wave format. According to scientific experts, this development can be understood as equivalent, […]

Definition of thermal radiation

Thermal radiation is the energy emitted in the form of electromagnetic waves by a body due to its temperature. It is the result of the movement of charged particles within matter, and all bodies with temperatures above absolute zero emit thermal radiation. Examples of Thermal Radiation Thermal radiation is a common phenomenon […]

Definition of magnetosphere

The magnetosphere is a region around a celestial body, such as Earth, dominated by its magnetic field, which acts as a protective barrier against charged particles from the solar wind and cosmic radiation. This magnetic bubble deflects and traps particles, creating structures such as the Van Allen belts and visible phenomena such as […]

Definition of emission spectrum

Emission spectrum is an expression associated with chemical compounds or elements that is used in the scientific field to refer to the frequency spectrum that arises in terms of the emission of electromagnetic radiation when there are electronic transitions in a molecule or an atom that range from high levels of energy to lower states. […]

Definition of quantum chromodynamics

Quantum chromodynamics is the name given to a quantum field theory focused on the strong interaction, a fundamental force framed in the standard model of particle physics. As noted when searching for information about the emergence of this type of gauge theory, it is content promoted by David Gross, David […]

Definition of inflation theory

The inflation theory is a cosmological model that proposes a rapid exponential expansion of the universe during its first moments, immediately after the Big Bang. This cosmic inflation phase would have occurred in a fraction of a second and explains several problems in the standard Big Bang model, such as temperature uniformity […]

Definition of Raoult's law

Raoult's Law is the name of a thermodynamic postulate that alludes to the French chemist and physicist who instituted it around 1887: François Marie Raoult. This principle indicates that the vapor pressure (considered at a partial level) of each of the constituents of an ideal mixture based on liquids […]

Definition of chemical potential

The chemical potential is a thermodynamic quantity that describes the capacity of a substance to do chemical work, that is, its tendency to participate in a chemical reaction or to diffuse in a system. It is defined as the change in the free energy of a system when an infinitesimal amount of the substance is added, […]

Definition of collision theory

Collision theory is the name that identifies an old postulate, still valid and useful on a universal scale, which between 1916 and 1918 was promoted by a German chemist named Max Trautz and the British professor and chemist William Cudmore McCullagh Lewis. This content, closely linked to chemical kinetics, […]

Definition of vapor pressure

Vapor pressure is an expression that refers to a phenomenon observed in closed systems at a certain temperature. It consists of a pressure exerted by the gas phase (or vapor) in the liquid phase when the latter and the vapor manage to reach a dynamic equilibrium. When investigating the characteristics, applications and scope of pressure […]
