Why is black such a good heat sink?
I think this is the answer, but I'm not so sure. The sun gives of different waves varied according to their wave length. We see different colors because for example green leaves absorbs all colors except for the color green which is reflected and bounced back to its surroundings causing us to see the color green. In black things, it absorbs all colors thus causing us to see black. In other words, it absorbs all the waves that is given of by the sun which makes it a heat sink.
What colour absorbs the most light?
A black non-shiny surface will capture more light. It is also the kind of surface which does not reflect the light which it has caught. Such a surface is also excellent at absorbing heat. It is the lighter colours and the shinier surfaces which reflect light. This makes one wonder why women in some hot countries, such as those in the northern parts of Africa wear black material which almost covers all of their body's surface.
What is the relationship between the heat of reaction and a chemical reaction?
The heat of reaction is the amount of heat energy released or absorbed during a chemical reaction. It is a measure of the reaction's energy change. The relationship between the heat of reaction and a chemical reaction is that the heat of reaction indicates whether a reaction is exothermic (releases heat) or endothermic (absorbs heat). This information helps us understand the energy changes that occur during the reaction.
Why is cold air cold?
Cold air feels cold because it has a lower temperature than our body temperature. When we come into contact with cold air, it absorbs heat from our skin, making us feel cold.
Why does a black can cool down faster than a white can?
The reason something looks black to us is because it reflects less light - therefore, the light is absorbed. The energy of the absorbed light, of course, heats the object up. Please note that black objects also tend to emit thermal radiation faster - so if there is no sunlight, they will get cold faster.
