Is a battery charging a physical or chemical change?
chemical; when charging, a chemical change is produced to provide energy for the phone.
When electricity from a battery causes a light bulb to light - is this a physical or a chemical change?
No pictures, but here are ten examples of physical and chemical change: Physical: melting, freezing, subliming, condensing, deposition, vaporizing, crushing, bending, tearing, mixing in a heterogeneous mixture. Chemical: combustion, rusting, baking, electroplating, yeast, acid and base neutralization, baking soda and vinegar, chemical battery, metabolism.
A physical change is different than a chemical change, because in a physical change, the composition of the matter did not change. While in a chemical change, the composition of the matter did change. SO basically, the composition of the matter does not change is the difference between a physical change and a chemical change. yes
