Is Dry Ice an Example of Deposition or Sublimation?

Learn why dry ice sublimates from solid to gas and why it is not an example of deposition in phase changes.

Dry ice is the solid form of carbon dioxide, and it sublimates directly into gas under normal conditions. Therefore, it is not an example of deposition, which is the phase transition from gas to solid without passing through a liquid state.

FAQs & Answers

  1. What is deposition in chemistry? Deposition is the phase change where a gas transforms directly into a solid without passing through the liquid phase.
  2. Why does dry ice sublimate instead of deposit? Dry ice sublimates because carbon dioxide transitions directly from solid to gas under normal atmospheric pressure and temperature without becoming liquid first.
  3. What are other examples of sublimation besides dry ice? Other examples include mothballs, iodine crystals, and snow in certain conditions sublimating directly into vapor.
