The color temperature scale describes only the color of light emitted by a light source, which may actually be at a different (and often much lower) temperature. [1] [2] Color temperature has applications in lighting, [3] photography, [4] videography, [5] publishing, [6] manufacturing, [7] astrophysics, [8] and other fields.
The kelvin (symbol: K) is the base unit for temperature in the International System of Units (SI). The Kelvin scale is an absolute temperature scale that starts at ...
The color temperature of a light source is the temperature of a black body that has the same chromaticity (i.e. color) as the light source. A notional temperature, the correlated color temperature, the temperature of a black body that emits light of a hue that to human color perception most closely matches the light from the lamp, is assigned.
An incandescent light bulb, incandescent lamp or incandescent light globe is an electric light with a filament that is heated until it glows. The filament is enclosed in a glass bulb that is either evacuated or filled with inert gas to protect the filament from oxidation .
Apart from absolute zero, it does not have a reference temperature. It is known as the Kelvin scale, widely used in science and technology. The kelvin (the unit name is spelled with a lower-case 'k') is the unit of temperature in the International System of Units (SI). The temperature of a body in a state of thermodynamic equilibrium is always ...
Also acid ionization constant or acidity constant. A quantitative measure of the strength of an acid in solution expressed as an equilibrium constant for a chemical dissociation reaction in the context of acid-base reactions. It is often given as its base-10 cologarithm, p K a. acid–base extraction A chemical reaction in which chemical species are separated from other acids and bases. acid ...
A definition of temperature can be based on the relationship: = The relationship suggests that a positive temperature corresponds to the condition where entropy, S, increases as thermal energy, q rev, is added to the system. This is the "normal" condition in the macroscopic world, and is always the case for the translational, vibrational ...
Thermodynamic temperature is a quantity defined in thermodynamics as distinct from kinetic theory or statistical mechanics.. Historically, thermodynamic temperature was defined by Lord Kelvin in terms of a macroscopic relation between thermodynamic work and heat transfer as defined in thermodynamics, but the kelvin was redefined by international agreement in 2019 in terms of phenomena that are ...
