It is a combination of both physical and chemical phenomenon..rubbing of the match against the box creates friction and thus creating heat which is a physical phenomenon.the heat produced then triggers a chemical reaction that lights the match stick
Yes, it is!
Lighting a match is a chemical reaction.
The reaction starts when a match head (made of sulphur, glass powder and an oxidizing agent) has been struck on a striking surface (made of sand, powdered glass and red phosphorus). Oxygen gas (a common oxidizing agent) is produced when the red phosphorus turns white, catching a small flame when the match strikes the striking surface (friction). The heat from the friction (small flame) and the oxygen help the sulphur on the match head to ignite, which helps the wood catch on fire.
An oxidizing agent is necessary for this reaction to keep the flame going.
flammability is a material's ability to burn in the presence of oxygen (chemical property)
"When candles burn, new substances form..."
this is the same for lighting a match
Yes, it is!
I think it is a chemical change
Physical
Lighting a match is a chemical change.
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.
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.
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.
