Yes, chewing on a bone is considered a physical change. During this process, the bone is broken down into smaller pieces, but its chemical structure remains unchanged. The act of chewing involves mechanical processes, such as grinding and breaking, rather than altering the bone's chemical composition. Therefore, it qualifies as a physical change.
Breaking glass is a physical change, as it does not change the chemical composition of the material.

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.
YES. It surely is NOT chemical but a physical change.If you think of the stick in terms of it is a solid, then you will understand that the broken parts have not changed their physical state, only their appearance.So its physical stateis not changed, but its (mechanical, or outer properties) form is changed by force.
Breaking, grinding, cracking are all examples of a physical change. The nature of the substance has not changed, just the size of the pieces has changed.
