Are phase changes physical or chemical in nature?
A phase change is a physical change. It is not a chemical change.
Another term for a chemical change is?
Another name of chemical change is a "chemical reaction".
Is a change in mass an indicator of chemical reaction?
No, it is NOT an indicator of a chemical reaction. Change in color IS an indicator of chemical change, though.
Is burned ethanol a physical or chemical change?
Burning anything (a liquid or a solid) is a chemical change and the reaction is known as a combustion reaction.
Is Gas produced from a reaction is a phase change and not a chemical change.?
A gas released during a chemical reaction is a chemical change.

Is water changing from liquid to gas a chemical reaction?
No, water undergoing a phase change is a physical change, not a chemical change.
Are phase changes physical or chemical in nature?
A phase change is a physical change. It is not a chemical change.
Evaporation and condensation are what reaction?
Not chemical reactions, but change of phases
Why is a phase change a physical change and NOT a chemical change?
Because no chemical reaction is taking place. It is the same substance, just in a different state of matter.
When a solution is heated and a gas is formed is that a chemical change?
If there is no chemical reaction occurring in the solution as a result of heating then this scenario constitutes a phase change.
Freezing involves a chemical reaction?
No, freezing involves phase change, which is a physical change. There is no chemical reaction, as the basic chemistry is unchanged it is still the same material in a different physical state.
How does carbon dioxide change?
chemical because it is changing the state from solid to a gas in which is a chemical change
What is a change that alters the form or appearance of a substance but does not make it into other substance?
It is considered a physical change. A chemical change involves chemical reactions that change the substance into another substance. A physical change typically only modifies the form or phase.
What is the process of changing gas to gas is called?
This change of phase doesn't exist; probable you think to a chemical reaction in gaseous phase.
Explain why burning butter is a chemical change but melting is not?
Melting: change of phase, a physical phenomenon without change of the composition. Burning: a reaction of oxydation, a change of composition - a chemical change.
