Difference between H II region and Temperature

H II region vs. Temperature

An H II region or HII region is a region of interstellar atomic hydrogen that is ionized. Temperature is a physical quantity expressing hot and cold.

Similarities between H II region and Temperature

H II region and Temperature have 13 things in common (in Unionpedia): Density, Gas, Hertzsprung–Russell diagram, Infrared, Ion, Kelvin, Molecule, Speed of sound, Sun, Supernova, Ultraviolet, Wavelength, X-ray.

Density

The density, or more precisely, the volumetric mass density, of a substance is its mass per unit volume.

Gas

Gas is one of the four fundamental states of matter (the others being solid, liquid, and plasma).

Hertzsprung–Russell diagram

The Hertzsprung–Russell diagram, abbreviated H–R diagram, HR diagram or HRD, is a scatter plot of stars showing the relationship between the stars' absolute magnitudes or luminosities versus their stellar classifications or effective temperatures.

Infrared

Infrared radiation (IR) is electromagnetic radiation (EMR) with longer wavelengths than those of visible light, and is therefore generally invisible to the human eye (although IR at wavelengths up to 1050 nm from specially pulsed lasers can be seen by humans under certain conditions). It is sometimes called infrared light.

Ion

An ion is an atom or molecule that has a non-zero net electrical charge (its total number of electrons is not equal to its total number of protons).

Kelvin

The Kelvin scale is an absolute thermodynamic temperature scale using as its null point absolute zero, the temperature at which all thermal motion ceases in the classical description of thermodynamics.

Molecule

A molecule is an electrically neutral group of two or more atoms held together by chemical bonds.

Speed of sound

The speed of sound is the distance travelled per unit time by a sound wave as it propagates through an elastic medium.

Sun

The Sun is the star at the center of the Solar System.

Supernova

A supernova (plural: supernovae or supernovas, abbreviations: SN and SNe) is a transient astronomical event that occurs during the last stellar evolutionary stages of a star's life, either a massive star or a white dwarf, whose destruction is marked by one final, titanic explosion.

Ultraviolet

Ultraviolet (UV) is electromagnetic radiation with a wavelength from 10 nm to 400 nm, shorter than that of visible light but longer than X-rays.

Wavelength

In physics, the wavelength is the spatial period of a periodic wave—the distance over which the wave's shape repeats.

X-ray

X-rays make up X-radiation, a form of electromagnetic radiation.
