Question

Если на палец резинку почему он делается сначала красным, потом фиолетовым, а затем белям?

Answer 1

Красный из за давление крови на кончике фиолетовый из за недостатка крови белый нет крови на пальце

Answer 2

Сначала кровь приливаетс, потом она там застаивается, а позже палец вроде "умирает"

Answer 3

Explanation of Color Changes in Rubber Band

When a rubber band is stretched, it undergoes a color change due to a phenomenon called "stress-induced crystallization." This occurs because the stretching of the rubber band causes the polymer chains within it to align in a particular way, leading to the observed color changes.

Red Color: The initial red color of the rubber band when stretched is due to the alignment of the polymer chains. As the rubber band is stretched, the polymer chains start to align in a way that causes the red color to become more prominent.

Violet Color: As the stretching continues, the alignment of the polymer chains changes, leading to the appearance of a violet color. This change in color is a result of the further alignment and rearrangement of the polymer chains within the rubber band.

White Color: Finally, the rubber band turns white when it is stretched to its maximum extent. This change in color occurs because the stress-induced crystallization causes the polymer chains to align in a way that scatters light, resulting in the appearance of a white color.

These color changes are a result of the complex molecular structure of the rubber band and the way its polymer chains respond to stress-induced crystallization.
