Drying clothes represents a physical change, not a chemical change. The process simply converts liquid water to gaseous water, so it's only a change in state.
The water is merely going from a liquid state to a gas state. Its chemical identity remains the same.
Drying clothes would be a physical change. The clothes themselves do not change either chemically or physically, so one needs to consider the removal or liquid water from the clothes. This is simply a phase change of H2O liquid to H2O vapor (steam). It is still H2O either way, so there is no chemical change. It would be a physical change.
No. Physical cause it hasn't changed its just gone from wet to dry :-)
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). :)
Sewing clothes is a physical change from fabric into clothes we can wear.

Ignition of a match is a chemical process.
Yes
Freeze-drying is a chemical change because it changes the actual composition of the object by removing water.
The drying itself is (always) a physical change.
