Is the sublimation of dry ice a physical or chemical change?
Understand the Problem
The question is asking whether the process of sublimation of dry ice is classified as a physical change or a chemical change. Sublimation refers to the process where dry ice (solid carbon dioxide) transitions directly from solid to gas without becoming liquid. Understanding the properties of states of matter will help clarify this.
Answer
physical change
The final answer is a physical change.
Answer for screen readers
The final answer is a physical change.
More Information
Sublimation is the process where a substance transitions directly from a solid to a gas without passing through the liquid phase. This is purely a physical change as the chemical composition of the substance remains the same.
Tips
A common mistake is to interpret sublimation as a chemical change due to the dramatic transition from solid to gas. Always remember to check if the chemical composition is altered.
