Neither - but when it does burn it's a chemical change.
physical
A neutralization reaction is a chemical change.
burning of compounds is a chemical change.
Elasticity is a physical property related to the ability of a material to deform and return to its original shape when a force is applied. It is not a change in the chemical composition of the material, so it is a physical property rather than a chemical change.
Dissolving is a physical change because it does not alter the chemical properties of the substance being dissolved. It involves the separation of particles within a substance without changing their chemical composition.
A physical state is physical and not chemical Physical Property is observed without changing a substance into another substance. Chemical property is the ability of a substance to change into different substance.
Examples: Iron Rusting: CHEMICAL CHANGE The ABILITY for Iron to rust: Chemical PROPERTY Ice freezing: Physical CHANGE Water's ABILITY to evaporate: Physical PROPERTY
It's a chemical change because a new substance comes out of tarnishing.
Stating that something is flammable is stating a chemical property. But the actual burning would be a chemical change.
A physical change
Melting ice cream is a physical change because it has the ability to go back to it's frozen form and be ice cream again. The chemical identity of it isn't changed.
No, electrical conductivity is a physical property that depends on the ability of a material to carry an electric current. It is not a chemical change because the chemical composition of the substance remains the same.
