Physical Change vs. Chemical Change
The difference between a physical and chemical change is that when a physical change occurs, the substance is the same it is just it looks different. When a chemical change occurs, the entire substance changes, like paper burning. All that is left of the paper is ashes. Ashes are a completely different substance than a match or fire.
Physical Property vs. Chemical Property
The difference between a physical and a chemical property is that a physical property is when you observe something without changing the substance of it. A chemical property is something you observe when one substance interacts with another substance and creates a whole new substance.
