I just had this question for a chemistry and it is a physical change

∙ 12y agoDry Ice is simply C02 that is solid. It doesn't change unless you change the temperature of the pressure. When it does, however, 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
What is dry ice physical or chemical change when left unattended?
Physical change, called sublimation. It still stays CO2
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 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.
Melting of ice chemical or physical change?
Melting ice is a physical change, because there is no new substance formed. The only thing that changes is the state of matter.
Is dry ice smoking at a concert is a physical or chemical change?
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 the temperature at which dry ice evaporates a chemical or physical?
Physical Change
Is mealting dry ice a chemical change or physical change?
Any type of melting 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 it physical or chemical when dry ice evaporates without melting as time passes?
It is a physical change because the composition of the dry ice didn't change; it just changed forms
Is freezing carbon dioxide to make dry ice a chemical change?
No, it's a physical change.
What is dry ice physical or chemical change when left unattended?
Physical change, called sublimation. It still stays CO2
Is dry ice subliamating into carbon dioxide a chemical change?
no. a phase change is ALWAYS a physical change in the substance.
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.
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.
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.
