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 frozen CO2 called dry ice?
Solid Carbon Dioxide is called dry ice because on sublimation, it directly changes to gas. It does not have an intermediate liquid state. Thus, when it is frozen, it does not melt. Therefore, as it does not change into liquid and is dry, it is called Dry ice.
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 turning into Carbon dioxide physical or chemical?
It is a physical change of state. CO2 solid (dry ice) is still CO2 as a gas.What does change is the physical heat content of the substance. By absorbing heat the physical state is changed from a solid at -109.3 degrees F to a gas at -109.3 degrees F. All the heat absorbed for the change of state is used by the molecules to expand in size (external energy), rather than to change in temperature. There is also a small amount of energy loss due to this change (entropy). Another calculation made is internal energy which is the internal molecular motive energy of the substance.
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 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.
Why the dry ice first time the smoke will move up aftera few mins the smoke move downwards?
because of the carbon dioxide in the dry ice because of the carbon dioxide in the dry ice because of the carbon dioxide in the dry ice
How do you make smoke without a smoke machine and dry ice?
start a fire
what is called when dry ice changing into smoke?
"sublimation"
Why did the dry ice smoke falls to the floor and flow downwards?
Dry ice, carbon dioxide, is more dense than air.
How can instantaneous smoke be produced by a reaction?
dry ice and water enjoy
Is dry ice a chemical change or a physical change?
I just had this question for a chemistry and it is a physical change
In the WWE what does Edge use for his entrance a smoke maker or dry ice?
I believe he uses a Smoke Machine for his entrance. If you look closely you can see them present on the ramp/stage area.
What are some cheap Halloween effects I can use in my yard haunt?
One of the best and cheapest effects is dry ice being used to create fake smoke. Dry ice can be found at your local supermarket. Then all you need to find is a fan to blow the dry ice "smoke" around the room.

What is the advantages of using dry ice on stages and in films?
It will create a smoke effect.
When dry ice gives off smoke what is the compound formed?
When dry ice appears to give off smoke it is solid carbon dioxide subliming to vapor. The "smoke" is thus carbon dioxide gas. Dry ice is also often used in the theatre/television/movies etc. because it is cold enough to condense water vapour in the air to produce fog that may resemble smoke. Please see the link.
