here it is.


Term used to describe a surface’s relative ability to absorb and reradiate heat. A surface with high emissivity will radiate heat faster than a surface with low emissivity. Emissivity is recorded on a scale of 0-1, where 0 would be the perfect white surface reflecting 100% of heat while 1 would be the perfect black surface that absorbs 100% of heat.
