| absolute temperature | temperature | Temperature measured on the Kelvin scale: 0 Kelvin = -273.15 ° Celsius. Absolute temperature is directly related to (kinetic) energy via the equation E = kBT, where kB is Boltzmann's constant. So, a temperature of 0 K corresponds to zero energy, and room temperature, 300 K = 27 °C, corresponds to an energy of 0.025 eV. | ||
| absolute zero | temperature | The lowest possible temperature, attained when a system is at its minimum possible energy. The Kelvin temperature scale sets its zero point at absolute zero (-273.15° on the Celsius scale, and -434.07° on the Fahrenheit scale). | ||
| color temperature | temperature | A stellar temperature determined by comparison of the spectral distribution of the star's radiation with that of a blackbody. | ||
| effective temperature | temperature | Teff | The temperature that a blackbody would have which emitted the same amount of energy per unit area as the star does: it is a temperature characteristic of the surface region. Teff of Sun, 5800 K. | |
| electron temperature | temperature | The temperature that appears in the Maxwell distribution of velocities for electrons. | ||
| kinetic temperature | temperature | A measure of the average random motion of the particles in a system. | ||
| radiation temperature | temperature | The temperature that a blackbody of similar dimensions would have that radiated the same intensity at the same frequency. |
