Breaking a brick is a physical change because it does not alter the chemical composition of the brick. The bricks remain chemically the same even after breaking into smaller pieces.
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.
When you break a light stick, it is a physical change, not a chemical change. The breaking of the light stick only changes its physical state but does not alter its chemical composition. This is because the chemical reactions that produce light in a light stick have already occurred when the stick was activated, and breaking it does not initiate any new chemical reactions.
Breaking a stick of gum is a physical change because the gum still retains its chemical composition even after it has been broken into smaller pieces. The breaking process only affects the physical properties of the gum, such as its shape and size, but does not change its chemical composition.
Breaking a lump of chalk into powder is a physical change, not a chemical reaction. The chemical composition of the chalk remains the same before and after breaking it into powder.

Actually breaking a dinner plate is not a chemical change. A chemical change is like putting sugar into a hot cup of water or tea.
Breaking glass is a physical change, as it does not change the chemical composition of the material.
A plate dropping and shattering is a physical change. It is not a chemical change, as the material used in making the plate doesn't change.
Since in breaking down there is no chemical change it's a physical change
It is a chemical change.
no, breaking wood is a physical change.If the wood was burned, that would be chemical change
A chemical change is when the molecules of an object / solution are changed. A physical change is when the object / solution is altered without molecular change. Breaking glass is a physical change.
Physical or chemical
No. After breaking the mirror, the chemical properties of the remaining pieces are the same as the intact mirror. This is a physical change, not a chemical change.
This is a physical change.
