Temperature is a physical quantity that expresses hot and cold.
Temperature may also refer to:
Dose means quantity in the fields of nutrition, medicine, and toxicology. Dosage is the rate of application of a dose, although in common and imprecise usage, the words are sometimes used synonymously.

Saturation, saturated, unsaturation or unsaturated may refer to:
Red Planet is a nickname for the planet Mars, due to its surface color. It may also refer to:
Retrograde may refer to:
Resistance may refer to:
Color or colour is the visual perceptual property corresponding in humans to the categories called red, yellow, blue, green, etc.
Static may refer to:
NET may refer to:
Bliss is a common noun meaning 'extreme happiness'. It may also refer to:

Black-body radiation is the thermal electromagnetic radiation within or surrounding a body in thermodynamic equilibrium with its environment, emitted by a black body. It has a specific spectrum of wavelengths, inversely related to intensity that depend only on the body's temperature, which is assumed for the sake of calculations and theory to be uniform and constant.
Overheating may refer to:
The emissivity of the surface of a material is its effectiveness in emitting energy as thermal radiation. Thermal radiation is electromagnetic radiation that may include both visible radiation (light) and infrared radiation, which is not visible to human eyes. The thermal radiation from very hot objects is easily visible to the eye. Quantitatively, emissivity is the ratio of the thermal radiation from a surface to the radiation from an ideal black surface at the same temperature as given by the Stefan–Boltzmann law. The ratio varies from 0 to 1. The surface of a perfect black body emits thermal radiation at the rate of approximately 448 watts per square metre at room temperature ; all real objects have emissivities less than 1.0, and emit radiation at correspondingly lower rates.
Flux is a rate of flow through a surface or substance in physics, and has a related meaning in applied mathematics.
Heat is energy in transfer to or from a thermodynamic system by mechanisms other than thermodynamic work or transfer of matter.
Time scale may refer to:
Blue Planet may refer to:
In thermodynamics, heat is energy in transfer to or from a thermodynamic system, by mechanisms other than thermodynamic work or transfer of matter. The various mechanisms of energy transfer that define heat are stated in the next section of this article.
Temperature is a physical quantity that expresses hot and cold. It is the manifestation of thermal energy, present in all matter, which is the source of the occurrence of heat, a flow of energy, when a body is in contact with another that is colder or hotter.
