Matter is anything with __________________ and volume
A ___________________________ is a form of matter with a uniform and unchanging composition.
Substances have specific, unchanging ___________________________ that can be observed.
Substances have both physical and chemical properties. ___________________________ properties can be observed without changing a substance’s chemical composition.
Color, hardness, and ___________________________ are examples.
Other properties cannot be observed without changing the composition of a substance. These are called ___________________________ properties. An example is the tendency of iron to form rust when exposed to air.
Drag each property as either physical or chemical.

All matter that we encounter in everyday life exists in one of three physical forms.
A solid has definite shape and volume.
A liquid has a definite shape and takes on the volume of its container
A gas has both the shape and the volume of its container.
The particles in a gas cannot be compressed into a smaller volume.
Liquids tend to contract when heated.
The particles in a solid are spaced far apart.
The particles in a liquid are spaced far apart.
The words gas and vapor can be used interchangeably.
