Why does amount of black body radiation emitted depend on temperature of object?
The hotter an object gets the faster its atoms vibrate.Vibration can be considered as a repeating cycle of accelerating, decelerating and then accelerating back again in the other direction.Accelerating charges radiate energyHence, vibrating atoms radiate energyHotter atoms vibrate more quickly so do more accelerating, so they emit more radiation!
What materials radiate heat?
All materials radiate heat equivalent to their temperature above absolute zero.This heat is called "black body" radiation. When the peak of the "black body" radiation from a material is in the infrared band we perceive it as heat, but the radiation is always radiant heat regardless of whether it peak is in the radio band, infrared band, visible band, ultraviolet band, x-ray band, etc.
Why is Ice a black body?
It's not. The term "black body" is used to describe a hypothetical perfectly black object that reflects no light at all .here the light refers to entire electromagnetic spectrum. Although the emissivity of ice is near about 0.95 hence it behaves more as black body (emmisivity = 1) than a white body. The reason is for ice to be near about black body is that ice is a very good absorber of radiation outside the visible region (eg for infrared rays ) . Hence ice is more a black body than a white body (as in appearance ).
Which has the lowest albedo a white sheet of paper a mirror the surface of a body of water or a black sheet of paper?
a black sheet of paper
What will happen when white light falls on an object which does not transmit light?
when white light falls on a body which doesnot transmitts light the either all the light is absorbed by body as like black body and stored it in another form of energy or all the light may get reflected as like white body.

What is a black and white sheep?
There are many black and white sheep. Such as the suffolk or hampshires. which have black heads and legs but a white body/wool.There are also Jacob which are piebald (black and white spotted).
If an object is black what does it absorb?
A black body absorbs most of the light that falls on it. A perfect black body will absorb all of the light but will radiate electromagnetic energy according to it's temperature according to plank's law. This is why we call a black hole a BLACK hole. It absorbs EVERYTHING which falls into it and not even light can escape.
What north American bird has a white body and black head?

Which color does the zebras stripes start with black or white?
if your asking "is a zebra white with black stripes or black with white?" im pretty sure they are white with black because their bellys are all white so the white is the color of the body and then there are black stripes on it.
What is a skunk body color?
black and white
A cow that has a white face and a black body is called?
Black Baldy
What is the best material for conducting and radiating heat?
Silver is about the best for conduction, with copper not far behind. For radiation, a black body is best, and will radiate more heat the hotter it is. The sun for instance acts as a black body with temperature about 6000 deg C.

Could that be an immature black widow male?
