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 added to dry ice to make it change?
Essentially, dry ice will simply change from a solid straight to a gas through sublimation at room temperature. Nothing is needed to change the state of matter of dry ice except a higher temperature.
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.
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 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 there any chemical change that can happen to dry ice?
no.
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.
What is causing the change in dry ice and the water ice?
Dry ice changes directly from a solid to a gas through sublimation. The change in water ice is due to melting, where heat energy is absorbed to break the hydrogen bonds holding the water molecules together, resulting in a phase change from solid to liquid.
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.
Can the temperature of dry ice change while experimenting?
Yes
Can a solid change into gas?
Yes. Dry ice, for example.
What is dry ice physical or chemical change when left unattended?
Physical change, called sublimation. It still stays CO2
