The disappearance of dry ice is primarily a physical change, as it sublimates directly from solid to gas without going through a liquid phase. This process involves a change in the state of matter, but the chemical composition of carbon dioxide remains the same throughout. Therefore, while the form of the substance changes, it does not involve a chemical reaction that alters its molecular structure.
What else can I help you with?
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.
Is there any chemical change that can happen to dry ice?
no.
Is mealting dry ice a chemical change or physical change?
Melting dry ice is a physical change because it is a change in state from solid to gas without altering the chemical composition of the substance.
Is dry ice smoking at a concert is a physical or chemical change?
The process of dry ice sublimating, or turning directly from a solid to a gas, is a physical change. No new substances are formed, just a change in the physical state of the dry ice from solid to gas.
What is the chemical formula of dry ice and ordinary ice?
Dry ice is solid carbon dioxide. It has the chemical formula CO2. The correct formula for dry ice( cardice), which is solid carbon dioxide, is CO2.

Why is dry ice disappearing a chemical change?
It isn't. Answer --> It is an example of phase change and thus a physical change. Not a chemical change
Is there any chemical change that can happen to dry ice?
no.
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
Is mealting dry ice a chemical change or physical change?
Melting dry ice is a physical change because it is a change in state from solid to gas without altering the chemical composition of the substance.
Is dry ice smoking at a concert is a physical or chemical change?
The process of dry ice sublimating, or turning directly from a solid to a gas, is a physical change. No new substances are formed, just a change in the physical state of the dry ice from solid to gas.
Is freezing carbon dioxide to make dry ice a chemical change?
No, it's a physical change.
Is dry ice subliamating into carbon dioxide a chemical change?
no. a phase change is ALWAYS a physical change in the substance.
Why is dry ice evaporation a physical chainge?
Dry ice is a solid form of cooled carbon dioxide. When it reaches room temperature it changes to gaseous carbon dioxide. Since, there is no change in the chemical composition of dry ice, it is called a physical change.
Is dry ice subliming a physical change or a chemical change?
A physical change. It's chemically still CO2, whether solid or a gas.
What is the chemical formula of dry ice and ordinary ice?
Dry ice is solid carbon dioxide. It has the chemical formula CO2. The correct formula for dry ice( cardice), which is solid carbon dioxide, is CO2.
