Explain physical and chemical change.
Physical is when a some properties of the material change, but the chemical composition stays the same.

What is the difference between extensive and intensive properties?
Extensive: Property is a property that depends on the amount of matter in a sample. This include mass & volume
Intensive: a property of matter that depends only on the type of matter in a sample and not on the amount. Other intensive properties include color, temperature, density, and solubility.
Give me an example of a homogenous and a heterogenous mixture.
