It is a physical change (phase change). Dry Ice is frozen carbon dioxide gas. At atmospheric pressure, liquid CO2 is unstable. So the frozen solid "sublimes" turning directly from a solid to a gas (absorbing heat from around it).

Physical Change
IF solid dry ice slowly disappears completely is this a physical or chemical change?
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.
What happens after a substance goes through a chemical change?
Yes because when a chemical change happens the substance may not have some of the physical or chemical properties it had once before. An example of htis would be Dry Ice. This would be an example because dry ice was once just ice then they add a chemical and it turns into dry ice.

Is dry ice changing into theatrical smoke physical or chemical 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.
Is dry ice a chemical change or a physical change?
I just had this question for a chemistry and it is a physical change

What is dry ice physical or chemical change when left unattended?
Physical change, called sublimation. It still stays CO2
