Is the evaporation of ether a chemical change?
No. Evaporation of ether or any other substance is a physical change as the identity of the substance remains the same.
How do chemicals differ from physical changes?
When matter undergoes a chemical change, the composition of the matter changes. When matter undergoes a physical change, composition of the matter remains the same.
Is steam turning into water chemical or physical?
Chemical changes are those in which the chemical composition of a substance changes during the process. But when steam turns into water or vice versa, only the physical state of the substance undergoes a change but the chemical composition remains same. Thus steam turning into water is a physical change.
Is it a physical or chemical change when a substance changes form but it remains the same substance?
it would be physical change because physical change is when the substance stays the same
What kind of change happens when the composition of a substance does not change?
Physical changes, such as the change from ice to water to steam; the compound remains as H2O in all three states.
Physical properties are altered but the substance remains the same kind of matter?
Melting ice to get water, or boiling water to get steam, doesn't change the identity of H2O.
What is the substance that undergoes a physical change but always stays the same?
a physical change is totally reversible, i.e, you can get the substance you will get back after some physical process like heating, evaporating, etc. thus the substance actually remains the same.
Is the evaporation of ether a chemical change?
No. Evaporation of ether or any other substance is a physical change as the identity of the substance remains the same.
Are broken pieces a chemical change?
No, it is a physical change as the identity of the substance remains the same. Broken glass is still glass.

Even if you change the shape and amount of a substance it's stays the same?
By changing the size, shape, or amount of a given substance, a physical change is being exerted. A physical change is a change in which the molecular structure of the substance remains the same. For a substance to be considered "changed", a chemical reaction must take place resulting in a reconfiguration of molecules. For example, with enough heat, wood undergoes a chemical reaction, converting it to carbon. Chipping a log with a hatchet, on the other hand, would entail a physical change.
Is condensation of water vapour is chemical change or a physical change?
It is a physical change as the identity of the substance remains the same.
What kind of change happens when the composition of a substance does not change?
Physical changes, such as the change from ice to water to steam; the compound remains as H2O in all three states.
