Question
Carbon dioxide changes from a solid – dry ice – to a gas at -78.5°C. Determine what type of change this is. Chemical reactionPhysical change
Solution
This is a Physical change. The transition of carbon dioxide from a solid (dry ice) to a gas at -78.5°C is a change in state of matter, which is a physical change. No new substance is formed in this process, which is why it's not a chemical reaction.
