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, or solid carbon dioxide, is the solid state of CO 2 gas below -109.3 Â°F (-78.5 Â°C). Dry ice does not occur naturally on earth but is man made. It is colorless. We can use dry ice for making drinks fizzy, killing gophers, and freezing warts. The vapor of dry ice causes suffocation and eventually, death.
