Lighting a match.
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). :)
Cutting hair is a physical change because it does not alter the chemical composition of the hair. The cutting process only changes the physical appearance and length of the hair without changing its chemical structure.
Cutting bread is a mechanical or physical change, not a chemical change.
Cutting your hair is a reversible physical change because it can grow back over time. The structure of the hair is not permanently altered by cutting it.
Cutting a circle out of a piece of paper is a physical change because the paper's chemical composition remains the same before and after the cutting. The change is only in the physical appearance and shape of the paper.

Well, honey, cutting snowflakes out of paper is indeed a physical change. You're physically altering the shape and size of the paper by snipping away at it. But hey, don't worry about it too much - it's just paper, not rocket science. Just keep on crafting those snowflakes and let your creativity fly!

No, cutting paper is a physical change, not a chemical change. The paper's chemical composition remains the same before and after cutting; only its physical shape is altered.
Cutting a piece of wood is a physical change because the chemical composition of the wood remains the same before and after cutting. The change is only in the physical appearance and shape of the wood.
cutting your hair is probably a physical change I don't know

Physical change.
Physical.
The cutting of wood is physical.
