PHYSICAL
Sharpening a pencil is a physical change because it does not alter the chemical composition of the pencil. The act of sharpening simply removes material from the pencil, making it shorter in length.
First off, its spelled "breaking". No, Its a physical change, because the pencil hasn't changed its chemical components, all you did was ruin a pencil. :)
This is a physical process.
Breaking a pencil in half could be an example of physical change, where the pencil's form is altered without changing its chemical composition.

No, erasing a mistake with an eraser is not a chemical reaction. It is a physical process where the friction of the eraser removes the pencil marks from the paper.
Yes it is a physical change because the pencil's chemical composition does not change.
Yes it is a physical change because the pencil's chemical composition does not change.
Breaking a pencil in half is a physical change, not a chemical change. The composition of the pencil, which is made of wood and graphite, remains the same even though its physical appearance has changed.
Sharpening a pencil is a physical change because it involves a change in the physical appearance of the pencil tip without altering its chemical composition. The process of grinding the pencil against a sharpener simply reshapes the pencil tip.
Sharpening a pencil is a physical change, because there is no change to the chemical makeup of the pencil when sharpening it. It is simply chunks of wood being sliced off to reveal more of the lead.It is a physical change.

It is a physical change. There are no changes made to the compounds in a pencil by breaking it.
physical, because you physically sharpen a pencil with a sharpener.
