Chemical Properties: The properties of a substance that can be used to identify it and that describes how the substance reacts with another substance resulting in a new substance. EX: Paper is Flammable, When something Rust
Ok so let's look at Physical properties first.
Chemical Change: A change in a substance that results in a different kind of substance and that cannot be reversed EX: A pancake cooking on a griddle, Hydrogen and oxygen Reacting to form water
Ok so now let's look at Physical Changes.
James is now taking Sarah to the Physical teaching room.
So do you understand now?
Yeah, I think I do. A Chemical Property is what could happen that would change a substance but a Physical property is what a substance looks like. A Chemical change is what happens to create a new substance and a Physical change is what happened to change the appearance no the substance.
Physical Properties: Characteristics of matter, size, shape, state that can be observed & measured EX: When water boils or when a substance dissolves in water.
Physical Change: A change in the property of a substance that does not create a new kind of matter. EX: When butter melts or when wadding up paper
So Now Sarah Understands the difference between a Chemical change/property and a Physical Change/ property.
