No.
Dissolving salt in water is a physical change because the salt molecules stay intact and only disperse in the water, without undergoing a chemical reaction.
Dissolving in water is a physical change.
Water boiling is a physical process; also dissolving. Rusting is a chemical process (oxidation).
Yes it is because no chemical reaction occurs during it so it is not chemical.
a physical reaction for the chemical structure is not changing.
No.
It is a physical because it didn't change the substance
Dissolving salt in water is a physical change because the salt molecules stay intact and only disperse in the water, without undergoing a chemical reaction.
No, this is pure physics
Dissolving in water is a physical change.
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
No, sugar dissolving in water is a physical change, not a chemical reaction. The sugar molecules are simply being dispersed in the water, without any new substances being formed.
Water boiling is a physical process; also dissolving. Rusting is a chemical process (oxidation).
Yes it is because no chemical reaction occurs during it so it is not chemical.
Dissolving salt in water is an example of a physical change. Although the ions of sodium and chlorine separate when the salt dissolves, no chemical reaction takes place.
It is not only a dissolution but also a chemical reaction; consequently a chemical change.
