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

∙ 13y agoA chemical change is when the composition of an object is subject to change, a physical change is when physical properties are changed. Obviously, when you sharpen a pencil, the pencil's composition does not change, but it's physical features are.

Why sharpening a pencil is a different type of physical change than freezing water to make ice cubs?
Although they both still have the same basic elements (i.e. pencil and lead vs water), there is a physical state change that occurs when you freeze water to make ice. Sharpening/shaving down a pencil only results in a difference of shape and size. It's about the same as ripping paper vs burning paper. Also, freezing water to make ice is a reversible change (you can melt ice to turn it back into water) and shaving a pencil is an irreversible change (you can't sharpen a pencil and then put the pencil shavings back onto the pencil.)
