According to the National Funeral Directors Association, the median cost of a traditional funeral is approximately $7045. This includes the cost of embalming and a metal casket. The purchase of the gravesite and a burial vault or liner can add as much as $3000 more to the $7045 cost.
Brightness temperature is the temperature a black body in thermal equilibrium with its surroundings would have to be to duplicate the observed intensity of a grey body object at a frequency.This concept is extensively used in radio astronomy and planetary science.the Intensity or Brightness) is the amount of energy emitted per unit surface area per unit time per unit solid angle and in the frequency range between and; is the temperature of the black body; is Planck's constant; is frequency; is the speed of light; and is Boltzmann's constant.
Color temperature is conventionally expressed in kelvin, using the symbol K, a unit of measure for absolute temperature. Color temperatures over 5000 K are called cool colors (bluish white), while lower color temperatures (2700â3000 K) are called warm colors (yellowish white through red).  Warm in this context is an analogy to radiated heat flux of traditional incandescent lighting rather than temperature.
