What are some chemical, extensive, and intensive properties of a pencil?

Answer 1

Physical properties: Properties that describe the look or feel of a substance.
Examples:
* Color
* Hardness - lead is soft
* Density
* Texture
* Shape
* Size
* Phase (solid, liquid, gas)
Choose 5 of those and look at a pencil.

Chemical properties:
Properties that relate to the ability of a substance to react with other substances, or to transform from one substance to another. The chemical properties of a substance relate to its chemical composition and the way the atoms in the molecules are chemically bonded together.

So, a wood will burn, producing CO2.
a pencil can write on certain objects, namely paper
the rubber on the eraser will melt (and smell)
the metal near the eraser will conduct heat (stay warm)
pencil lead is usually graphite (Amorphous Graphite) and graphite's chemical properties include: conduct electricity
