We see color based on the way objects reflect light. Different wavelengths of light are different colors, and the light that an object reflects is what we see. For example, a red ball reflects red light, and so we see the ball as red. Any light that the object doesn't reflect is absorbed, so the red ball would absorb all the light that isn't red. This light then turns into heat. In science, white is the absence of light, and so white objects reflect all light. This means that the object isn't absorbing any light, and so the object isn't absorbing any heat.

If pieces of black paper and white paper are laid on snow in sunshine what is likely to happen?
The snow under the black paper will melt faster as the paper absorbs the heat while the white paper reflects it.
Which color reflects heat the most - black or white?
White reflects heat the most because it absorbs very little. Black absorbs a lot of heat, so reflects very little.
What reflects more heat aluminium foil or white cardboard?
Aluminium foil reflects more heat than white cardboard.
Why is black paper a good conductor?
Black is way better than white because it absorbs heat whereas white reflects it. The black is also giving off its own radiation!
Why does a sheet of paper appear white?
Because the material it is made out of only reflects white light.
Why does black paper absorb light faster than white paper?
This is because back aborbs heat where as white reflects heat

Why black paper give out heat best?
Colour depends on what light something absorbs and reflects, white paper reflects all light so its white, and black absorbs all, thus, absorbing more light, and transmitting infra red waves

White reflects heat the most because it absorbs very little. Black absorbs a lot of heat, so reflects very little.
What reflects more heat aluminium foil or white cardboard?
Aluminium foil reflects more heat than white cardboard.
What protects items from heat?
Wrap it in something white. White reflects heat from the sun, keeping it cooler.

Black is way better than white because it absorbs heat whereas white reflects it. The black is also giving off its own radiation!
Which color rock would get the hotest a white or black?
Black absorbs heat, while white reflects heat away.
Why does a sheet of paper appear white?
Because the material it is made out of only reflects white light.
Why does black attract the heat?
the dull flat black absorbs every wavelength of visible light. this absorption creates heat, just like when you stand in the sun. white reflects all "colors" but white so it reflects most of the heat, but not all. a mirror reflects all light so it will be even cooler than a white surface.
Why is radiation of heat larger in a black surface than a white surface?
A black surface absorbs the heat radiation and a white surface reflects the heat radiation
Why do blach cars get hotter than white cars?
Black absorbs heat, while white reflects the heat and remains slightly cooler.
