Purple is defined as a deep, rich shade between crimson and violet, or, more broadly, as a range of hues of color between blue and red, or as a dark color that is a blend of red and blue.
Dry ice is the solid form of carbon dioxide (CO2), a molecule consisting of a single carbon atom bonded to two oxygen atoms. Dry ice is colorless, non-flammable, with a sour zesty odor, and can lower the pH of a solution when dissolved in water, forming carbonic acid (H2CO3).
If you hold a piece of dry ice too long, it feels like it is burning your skin. Your skin isn't actually burning, though. What is actually happening is that the dry ice is freezing your skin. The dry ice is carbon dioxide that has been frozen at -110 Â°F (-79 Â°C). That's why it hurts when you hold it too long, because your skin is starting to freeze from its cold. Freezing skin is a bad thing, so I recommend not letting dry ice âburnâ you. The reason that freezing and burning can feel the same is because touching things that are very cold can do the same thing to your cells as touching things that are very hot.
