No, breaking rock into small pieces is a physical change because the chemical composition of the rock remains the same. It is merely a change in the physical appearance of the rock.
The production of smoke from something burning would be a sign of a chemical change. Broken pieces, change in shape, or change in state are all physical changes.

False. Changing the size and shape of pieces of wood is a physical change, not a chemical change. A chemical change involves the alteration of the chemical composition of a substance, while a physical change only affects the physical properties of a substance.
The production of smoke from something burning would be a sign of a chemical change. Broken pieces, change in shape, or change in state are all physical changes.
Cutting wood into 10 pieces is a physical change because the wood's chemical composition remains the same. The change only affects the physical state of the wood by breaking it into smaller pieces.
Breaking coal into pieces is a physical change because it does not alter the chemical composition of the coal. The coal remains composed of the same elements before and after being broken into pieces.

No, a solid breaking up into many pieces is a physical change because the substance's chemical composition remains the same.
This is both a physical and chemical change. The explosion involves the release of energy (heat and light), which is a chemical change due to the breaking of chemical bonds. The breaking of the wrapper into many pieces is a physical change as it does not involve any change in the chemical composition of the materials.

No, making chalk dust is a physical change, not a chemical change. It involves the breaking down of the solid chalk into smaller pieces without altering its chemical composition.
