Sublimation is when a solid turns directly into a gas without becoming a liquid first. Common examples include dry ice (solid carbon dioxide) converting directly into CO2 gas and snow or ice turning into water vapor in sub-freezing temperatures. Deposition is when a gas changes directly into a solid. Examples include frost forming on cold surfaces from water vapor in the air and soot particles forming from gas in combustion engines.
FAQs & Answers
- What is sublimation in chemistry? Sublimation is the process where a solid turns directly into a gas without passing through the liquid phase.
- Can you give an example of deposition? Deposition occurs when a gas changes directly into a solid, such as frost forming on cold surfaces from water vapor.
- Why does dry ice sublimate instead of melting? Dry ice sublimates because it transitions directly from solid carbon dioxide to gas at atmospheric pressure, without becoming a liquid.
- How does frost form through deposition? Frost forms when water vapor in the air changes directly into solid ice on cold surfaces, bypassing the liquid phase.
