The red cloth and the white cloth absorb heat quickly

Red cloth, of course! Because heat is mainly due to the red rays in the sun, and the red cloth is the best absorber of red rays, it absorbs heat quickly!

The third floor is not right, according to this statement, the white cloth does not absorb all the light, and it absorbs heat faster? And the most heat in sunlight is infrared rays, not red light! The reason should be:

The white cloth has the strongest ability to reflect light, and the darker the cloth, the stronger the ability to reflect light, that is, the white cloth absorbs the least light, and the dark cloth absorbs more light, so the red cloth absorbs heat faster than the white cloth! That's why we're used to wearing white clothes in summer and dark clothes in winter!

Red cloth. Tarzan Chaoyang And the red cloth is the best absorber of red light - a theoretical mistake! The reason why red cloth is red is that it does not absorb red light!

Daylight has seven colors.

Theoretically, the white cloth can reflect all seven colors back (in fact, it still absorbs a small amount of light). So it absorbs less heat.

The red cloth theoretically absorbs the red light completely and reflects the remaining six kinds of light back. (In fact, a lot of red light is absorbed, and a small amount is reflected back.) The remaining six types of light are absorbed in small amounts and reflected back in large quantities. So red cloth absorbs heat faster than white cloth.

Red cloth. It should be that the darker the color, the stronger the heat absorption.

Dark color absorbs heat quickly: red cloth.

**Topic: The heat absorption capacity of the object is related to the color of the surface of the objectConjecture or hypothesis: the darker the color of the surface of the object, the stronger the heat absorption abilityDesign experiments and conduct experiments:

1) Main equipment and devices: three identical flasks, water, three thermometers 2) Experimental procedure design:

Paint each of the three flasks black, gray, and white, fill them with the same amount of water, and insert a thermometer into each of them. Place the three flasks in the sun at the same time, and after a while, record their respective temperatures t1, t2, t3

Design of Experimental Phenomena or Data Records Lu Xian**:

Analysis and Argumentation:

If the conclusions reached by the potato are consistent with your conjecture, then the phenomenon you have seen in the experimental procedure you have just designed.

It should be: t1>t2>t3

Evaluation: What do you think are the main factors that affect the effectiveness of the experiment in this design?

whether the thickness of the pigment is the same, etc.
