Explain physical and chemical change. 

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

Chemical is when the chemical composition changes

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.
