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 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.
What will happen to ethanol alcohol when you leave it in a watch glass?
it will dry up. chemical reaction happened
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 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.
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 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.
Why is dry ice disappearing a chemical change?
Dry ice disappearing is a physical change, not a chemical change. When dry ice sublimes (changes directly from a solid to a gas), the molecules are still CO2; no new substances are formed.
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 subliming a physical change or a chemical change?
A physical change. It's chemically still CO2, whether solid or a gas.
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 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 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.
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.
What will happen to ethanol alcohol when you leave it in a watch glass?
it will dry up. chemical reaction happened
What can be added to dry ice beside water to bring about a chemical change This is for a science product for fifth graders?
water does not induce a chemical change in dry ice, the warmth of it induces a 'state' change, from solid frozen state co2 to gaseous state co2. you can use a hair dryer or any other heat source. to chemically alter the co2, put a plant beside it, it will change it to oxygen and water for you.
