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.
Depends on the form of disintegration. If the pencil is being shaved down to sharpen its point, it is under going a physical change. If the pencil was being burnt or placed in a tank of acid, it would undergo a chemical change. By definition, a chemical change is one that changes the composition of the substance. A physical change changes the physical aspect of a substance.
Yes it is a physical change because the pencil's chemical composition does not change.
no it is a physical property cause you can still tell it is a pencil (smart ones)
It is a physical change, because you have not altered the chemical composition of matter, you have only changed its shape.
No, it is a physical change.

No, It's a physical change.

No. it is a physical change.
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
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.
Collor: yellowSmell: like woodTexture: smooth, graphite has layers
Yes, as it's still glass. There is no chemical/molecular change.
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.
Nope - it's a physical change. The chemical composition of the pencil is still the same !
It is a physical change. There are no changes made to the compounds in a pencil by breaking it.
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. :)
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.
That is a physical change. The is no chemical change that takes place when you sharpen your pencil in a standard manner. I suppose if you sharpen it extremely fast, you could catch the pencil on fire, which would then be a chemical change.
Breaking glass is a physical change, as it does not change the chemical composition of the material.

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
