why does the colour of the sticker on the pizza box change when you apply heat to it?
The pizza box stickers are made with a thermochromic ink that responds to changes in temperature. When the pizza box is heated, the ink changes from its original color to a new color, creating a color-changing effect.
The thermochromic ink contains thermochromic pigments that are sensitive to temperature changes. These pigments have molecules that rearrange in response to temperature, causing a change in color. When the box is heated, the ink changes color and when it cools down, it returns to its original color.
No, the color change is temporary and reversible. The color-changing effect will occur every time the pizza box is heated. Once the box cools down, the ink will return to its original color.
