Yes, lighting a match from a matchbox is a chemical change, not a physical change. When the match is struck, the chemicals on the match head react to produce heat, light, and a flame. This transformation is a chemical reaction, not just a change in physical state.
Lighting a match involves the conversion of chemical energy stored in the match head into thermal energy due to the friction when striking it against the matchbox. This thermal energy then further ignites the match head, leading to the release of light energy in the form of a flame.
Yes, lighting a match is a chemical change because the chemicals in the match head undergo a chemical reaction when exposed to heat from friction, resulting in the release of energy in the form of light and heat.
Yes, lighting a matchstick is a physical action that involves striking the match head against a rough surface to produce friction and heat, which ignites the match.
The energy processed by a matchstick in a matchbox is chemical energy stored in the match head that is released as heat and light when the match is struck and ignites.
Striking a match is a physical change because it can be reversed by extinguishing the flame. The chemical composition of the match does not change during this process.
lighting a match from a matchbox 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 is a chemical change because the molecules in the matchstick undergo a chemical reaction when exposed to heat, resulting in the production of new substances like ash and smoke.
Lighting a match is not a physical change because it involves a chemical reaction that produces heat and light, resulting in the transformation of the matchstick. Drying wet clothes and cutting snowflakes from paper are physical changes because they involve a change in appearance or state of matter without altering the chemical composition of the substances.
When a match is lit, the chemicals in the match head undergo a chemical reaction resulting in the production of heat, light, and new chemical compounds like carbon dioxide and water vapor. This transformation of the chemical composition of the match represents 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). :)

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.
