Is breaking coal into pieces chemical or physical change?
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.
Is changing the size and shape of pieces of wood a chemical change true or false?
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.
Is cutting wood into 10 pieces a physical or chemical change?
That change would be physical, since the chemical identity of the wood has not been altered by cutting it.
Is a solid breaking up into many pieces a chemical change?
Disintegration can be a chemical change, but it depends on what kind it is. For example, sharpening a knife is a physical change, but burning a piece of wood is a chemical change.
When a firecracker explodes giving off light and heat and breaking the wrapper into many pieces is that a physical change chemical change or both?
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.
