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.
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 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 the temperature at which dry ice evaporates a chemical or physical?
The temperature at which dry ice evaporates is a physical property. It is the sublimation point of carbon dioxide, where it changes directly from a solid to a gas without passing through the liquid phase.
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 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.
If you leave an orange out for days and there is nothing but the juice is dry will that be a chemical physical change?
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
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 hanging wet towels a chemical or physical change?
It is a physical change. Being changed from wet to dry.
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.
When you shower and your wet hair begins to dry is that a chemical change?
No, the drying of wet hair is a physical change, not a chemical change. The change in state from wet to dry is due to the evaporation of water and does not involve any chemical reactions altering the composition of the hair.
What is dry ice physical or chemical change when left unattended?
Physical change, called sublimation. It still stays CO2
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 dry ice subliming a physical change or a chemical change?
A physical change. It's chemically still CO2, whether solid or a gas.
Is freezing carbon dioxide to make dry ice a chemical change?
No, it's a physical change.
