The chemical composition is not changed.
The chemical composition is not changed.
A change from one liquid to another is typically considered a physical change rather than a chemical change. This is because the chemical composition of the substances involved remains the same during the transition.
ANSWER:Its a physical change. If you burned it and it became ash, its a chemical change. Physical change means it made no change on a molecular level. Its still paper, just in two separate pieces.It is a physical change, as the chemical property of the paper remains unchanged.
No. The cheese is still cheese, it's just in pieces now.
No, mixing two chemicals together is a physical change because the substances retain their original chemical properties. The chemical composition remains the same even though they are physically combined.
The chemical composition is not changed.
Colorless is a physical property. Determining change requires you to compare two things.
no, technically there is no such thing as a physical reaction. It is, however, a physical change. when two things react, it is chemical so you cannot have a "Physical" reaction in chemistry
It's a physical change
Is the Test tube sealed airtight or open air? Dissolving is a physical change.
A change from one liquid to another is typically considered a physical change rather than a chemical change. This is because the chemical composition of the substances involved remains the same during the transition.
There are two kinds of changes - physical and chemical. It depends on how the change is made.
It encountered a physical change.
A type of change in which the form of matter is changed to another form is called a physical change. Thus the chemical change does not occur, but only a physical change occurs in it. Example: When ice melts into water When water is boiled, and it changes into water vapor.
Density and specific internal energy are two physical properties that change with temperaturea change in temperature.

Physical, because each slice of pellet is still the same chemically: you have merely divided your one sodium block into two blocks of sodium. If it were chemical, some kind of notable chemical difference would have occurred (you would no longer have sodium, but something else).
