Sublimation is a physical change.
It is a physical change.
Any type of melting is a physical change.
Dry ice doesn't "turn into smoke". Dry ice causes moisture in the air to condense, forming fog. This is a purely physical, not chemical, change.
I just had this question for a chemistry and it is a physical change
Temperature is a physical change- it can be undone.
It isn't. Answer --> It is an example of phase change and thus a physical change. Not a chemical change
The sublimation of dry ice into gaseous carbon dioxide is a physical change. It does not undergo any chemical changes.
The "disappearance" of dry ice is a physical change. What you refer to as disappearance is actually sublimation where the solid CO2 turns to a gas without going through the liquid phase. Dry is is solid CO2 and when it disappears it becomes gaseous CO2, so it is a physical change.
