Chemical Properties
Of Matter
Definition
A chemical property is a characteristic that is observed when a substance interacts with another substance. Chemical properties are usually difficult to undo.
Examples
Some Examples could be when;
1. A magnet picks up a paper clip, you can see that the paper clip is magnetic
2. You drop mentos into a coke bottle and there is a lot of fizz that comes out (reactivity)
3. A log is exposed to water and rots (decay)
Examples
Combustion
Wood is combustible because when you light the fire, the fire burns the wood and turns it into ashes, yet the rest of the wood still lets the fire burn.
Rust
A rusted bike can be a chemical change because when the steel was exposed to water during rain, the rust was created, and it is difficult to undo.
Toxicity
Gasoline is toxic because if you drink gasoline it could cause stomach irritation and you could die or get very sick.
Non Examples
Some non-examples could be when;
1. Aluminum foil is malleable
2. Silly Putty is ductile
Non - Examples
Malleability
Aluminum foil being malleable is not a chemical property because it does not need to interact with another substance to change.
Ductility
Silly putty being ductile is not a chemical property because it is not reacting to something for you to notice it is ductile.
Temperature
Temperature is not a chemical property because there are not two substances that interact and have something to observe.
