Is dry ice subliming a physical change?
It is a physical change because even though it is a gas, it can be made back into what it used to be. Just like ice melts into water and water heats and evaporates to gas. Water can easily be frozen back to ice. Gas can turn back to water. Dry ice sublimating is a physical change of carbon dioxide between a solid state and a gaseous state without going through a liquid state. If it were s chemical change, than it would no longer be carbon dioxide after changing state.
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
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.
Is drying of fish is a chemical change?
No, drying of fish is a physical change, not a chemical change. The process of drying simply involves the removal of water from the fish, causing it to undergo a physical transformation, but its chemical composition remains the same.
What is a physical change A fermenting grapes to produce wine B baking a cake C a tomato ripening D dry ice subliming E digesting a meal?
D. Dry ice subliming is a physical change. Chemically, it's still CO2.

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 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.
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 turning bread into toast a physical or chemical change and why?
It is both. You dry the moisture out of the bread. However, the browning is a chemical change, as the chemical bonds are changed.
When solid dry ice gets warmed and changes into a gas a physical or chemical property?
The process is a physical process and the actual change is a physical change.
