Because you cant put the shards of pencil back on the pencil.

Breaking a pencil in half could be an example of physical change, where the pencil's form is altered without changing its chemical composition.
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. :)
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.
a physical change
Yes it is a physical change because the pencil's chemical composition does not change.

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.
It is a physical change. There are no changes made to the compounds in a pencil by breaking it.
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.

Jose got no pencils sharpend
physical, because you physically sharpen a pencil with a sharpener.
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.
PHYSICAL
No
Because the pencil is made of wood and you only changed the size and shape of the wood or pencil and did not change what the wood is made of the substance
