Kinds of temperature :

• absolute temperature (2 facts) - Temperature measured on the Kelvin scale: 0 Kelvin = -273.15 ° Celsius. Absolute temperature is directly related to (kinetic) energy via the equation E = k_BT, where k_B 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 (2 facts) - 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 (2 facts) - A stellar temperature determined by comparison of the spectral distribution of the star's radiation with that of a blackbody.
• effective temperature (3 facts) (T_eff) - 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. T_eff of Sun, 5800 K.
• electron temperature (2 facts) - The temperature that appears in the Maxwell distribution of velocities for electrons.
• kinetic temperature (2 facts) - A measure of the average random motion of the particles in a system.
• radiation temperature (2 facts) - The temperature that a blackbody of similar dimensions would have that radiated the same intensity at the same frequency.
