chemical change
Mop
The answer is lighting a match box because when doing so, the match goes into flames and flammability is a chemical change. When cutting a snowflake, the substances do not change, neither does it change when drying wet clothes. The person earlier said drying wet clothes, but he/she is wrong because when you dry wet clothes, the water goes through a physical change called evaporation, which is NOT a chemical change. I hope this helps. Good luck on your chapter assessments(I'm doing mine too). :)
Examples of chemical changes: * Burning of paper * Rusting of iron Examples of physical reactions: * Melting of ice * Melting of wax
Is the lighting of a bulb a reversible or an irreversible change
Lighting a match.
The sulfur on the match catches fire from friction as it is struck on the matchbox.
Mainly chemical (oxidation).
This is a little tricky. Striking a match is a physical act, but it does induce chemical changes. It depends on exactly what you mean by "lighting", ultimately. The end result is definitely a chemical change.
lighting a match from a matchbox is a chemical change.
yes lighting a match is a chemical change
Ignition of a match is a chemical process.

No Physical changes are state changes such as freezing, melting, evaporation, condensation, boiling. Physical changes do not produce "new" substances. Lighting a match would be an example of a chemical change in which the substances on the match, and eventually the wood or paper of the match are chemically altered to produce water, carbon dioxide, and other "new" compounds.
