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.

If I had to guess, there are hundreds of different physical changes at school. Some good examples are when you sharpen your pencil, write on paper, or cut your lunch with a knife or fork. These examples are just a few ways that physical changes take place at school.
When you sharpen a pencil, the wood and graphite are shaved down to create a finer, sharper tip. You can tell the pencil is sharp by looking at the tip - it will be pointed and no longer dull or flat. Additionally, the pencil may feel lighter as material has been removed during the sharpening process.
Yes it is a physical change because the pencil's chemical composition does not change.
physical, because you physically sharpen a pencil with a sharpener.
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.
Because you cant put the shards of pencil back on the pencil.
The hardness of the pencil lead affects how dark and easily it writes, softer leads are darker and create thicker lines while harder leads create lighter, thinner lines. The shape and size of the pencil barrel impact how comfortable the pencil is to hold and write with. The eraser material on the end of the pencil determines how effectively mistakes can be corrected.
