If a surface is black, it means it is not reflecting light. Instead of reflecting the light it is absorbig it into the pigment or material. Absorbed light energy is turned to heat. It radiates heat.

i thought this would be easily comprehendable.
look at it at the molecular level.
Though, if you discount plasticisers, paints and surface coatings, what kind of an object could you class as 'black'? im stumped... must be still half asleep.. i will get back to myself with this one.
