Pure Substances
This is a substance made of only one kind of atom
Element
This type of matter is made of two or more substances that are physically combined, not chemically.
Mixtures
This is anything that has mass and takes up space
Matter
What type of property can be observed without changing the substance's identity
Physical property
When water freezes into ice, it shows this type of change.
Physical Changes
This type of pure substance is made when two or more elements are chemically combined in fixed ratios.
Compound
Salt water and air are examples of this type of mixture, where the substances are evenly spread out and uniform.
Homogeneous Mixture
This property has to do with how much mass is compacted into something
This type if property describes how a substance reacts to form something new
Chemical Property

A salad or a bag of tail mix is an example of this type of mixture, where you can see the different parts and they are not uniform.
Heterogeneous Mixture
Name the four types of matter
Solid, Liquid, Gas, and Plasma
Density, color, and boiling point are examples of this type of property.
Physical Property

Physical Change
Table salt (NaCl) and water (H2O) are examples of this type of pure substance
Compound
The main way to separate mixtures is by using a technique, such as filtration, evaporation, or distillation
Physical Methods/Separation Methods
The movement of what must increase, for changes of state of matter to occur.
Energy
Flammability and reactivity with acid are examples of this type of property.
Chemical property
Burning wood creates new substances like ash and gases, which makes it this type of change.
Chemical Change
Oxygen (O2), gold (Au), and helium (He) are all examples of this type of pure substance.
Elements
This term describes a mixture where one substance dissolves completely in another, like sugar in tea.
A solution
This type of energy comes from the motion of particles in matter
Thermal energy
The ability of a metal to be hammered into sheets is this physical property.
Malleability
A sign of this type of change may include color change, bubbling, odor, or energy being released.
