Question
The process of using dry ice to preserve an ice cream is an example of ___________ process
- Sublimation
- Condensation
- Deposition
- De-Sublimation
Hint:
Dry ice is solid carbon dioxide.
The correct answer is: Sublimation
- Condensation is the process of conversion of gas to liquid.
- Sublimation is the conversion of a solid to a gas without being converted to an intermediate liquid.
- A deposition is the phase transition of gas to solid without being converted to intermediate liquid.
- De-sublimation is similar to deposition.
- The process of using dry ice to preserve an ice cream is an example of sublimation. Dry ice is solid carbon dioxide it sublimates.
