Understand the Problem
The question is asking what occurs when dry ice transitions from a solid state to a gaseous state as it sublimates; it seeks to understand the physical and chemical changes involved in this process.
Answer
Dry ice turns into carbon dioxide gas when it 'melts.'
The final answer is that as dry ice 'melts,' it turns into carbon dioxide gas, a process known as sublimation.

The final answer is that as dry ice 'melts,' it turns into carbon dioxide gas, a process known as sublimation.
More Information
Dry ice is the solid form of carbon dioxide and sublimates into gas at temperatures above -78.5°C (-109.3°F). This process is unique because it bypasses the liquid state entirely.
Tips
Common mistakes when dealing with dry ice include improper ventilation and handling without protective gear, leading to potential CO2 buildup or contact burns.
