What kind of energy conversion is lighting a match an example of?
Chemical potential energy being converted to heat energy
What are the examples when friction is desirable?

What processes is not a physical change drying wet clothescutting snowflakes out of paper lighting a match from a matchbox?

What process is not a physical change drying wet cloths cutting snowflakes out of paper lighting a match from a matchbook?
Ignition of a match is a chemical process.
What one what processes is not a physical change drying wet clothes cutting snowflakes out of paper lighting a match from a matchbook?
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). :)
Is Lightening a match a physical change?
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.
