I remember that in summer, the sun was like fire. My mother took me to the mall to buy clothes. I chose a black shirt, but my mother didn't want to and said, "You can't choose dark clothes, it absorbs heat easily!" " After listening to my mother's words, a lot of small question marks appeared in my mind, so I asked my mother inexplicably, "So, light and color still give off heat?" Mother finally showed a gratified smile, nodded and said, "Yes! "I am dubious, thinking: Why didn't I think about this question ~ ~ But I really like this dress!" At this time, my mother solved the problem and asked me to do a small experiment. So, I forgot to buy clothes and went home with my mother.

When I got home, my mother said, find a black cloth and a white cloth. It was carefully placed on the balcony, and in order to make the cloth heated evenly, I also held an exhibition on the balcony.

The bright sunshine shines on two pieces of cloth, which instantly lights up, just like bright diamonds, especially dazzling. In this way, I will look at the sun for a while, look at these two pieces of cloth for a while, and touch them from time to time. 10 minutes passed, and I couldn't wait to touch these two pieces of cloth, but the feeling was the same. I was suddenly disappointed. At this time, my mother couldn't bear to see my lost face, so she comforted me and said, "Don't lose heart, how long will it take!" Be patient ~ "After listening to my mother's encouragement, I felt like I had taken some specific medicine, and suddenly I became cheerful and waited patiently.

Ten minutes passed, and by this time, I was already sweating. I touched the black cloth weakly, and sure enough, the black cloth was very hot and steaming. I touched the white cloth again, not that it was cold, because it was impossible. It's a little hot, but the surface feels cool, not as hot as black cloth.

I am surprised and puzzled: why does black cloth absorb heat and white cloth dissipate heat? With all kinds of questions, I searched the internet for relevant information. It was found that the white object actually reflected all the light, but did not absorb it. Black objects, on the other hand, will absorb all the light and will not reflect back at all, so they are black. Light energy generates heat, and black absorbs all the light, so it naturally absorbs heat faster than white, but black dissipates heat faster, because black absorbs a lot of heat, so it releases heat when it absorbs too much heat, so it can absorb more heat.

Knowing this, I suddenly became enlightened. I see: you must consider everything more to make a better discovery!
