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).
Dry ice is the solid form of carbon dioxide (CO2). It's called dry ice because it does not melt like wet ice. Instead, dry ice converts into carbon dioxide gas. Because dry ice is extremely cold ( -109Â°F/-78.5Â°C), non-toxic, and completely dry, it is commonly used as an expendable refrigerant to ship frozen food or medical products or to cool materials during production.
