The temperature within the black box was warmer than the rest of the boxes because the black colour absorbs more heat than white or other light colours. The reason for the black house being warmer is because of the way the sunís rays are absorbed by that colour. Light colours donít get as hot because they reflect the sunís rays. In conclusion, an objectís colours are determined by frequencies of the sunís rays that reflect or absorb. If all the rays are reflected the object will appear white. If they are absorbed they appear black. Other colours are determined when both absorption and reflection take place at the same time. This shows that my hypothesis was correct.
