1. **Dry ice subliming (changing directly from a solid to a gas)**:
- **Physical Change**: This is a change in the state of matter without altering the chemical composition of the substance. Dry ice (solid carbon dioxide) changes to gaseous carbon dioxide, but the chemical makeup remains the same.
2. **The sulfur in eggs is able to turn a silver spoon black**:
- **Chemical Change**: This reaction indicates a chemical change because the sulfur reacts with the silver to form silver sulfide, resulting in a change in the chemical composition and appearance of the silver spoon.
