PROPERTIES OF MATTER

MATTER• What is matter?• States (phases) of matter• Properties of matter?

– Physical properties– Chemical properties– Characteristic properties

• Changes in matter• Types of matter

What is Matter?

Matter is the “stuff” that makes up everything.Matter is anything that has mass and takes upspace (volume). Therefore matter is anything

that has DENSITY!

PROPERTIES OF MATTERPROPERTIES OF MATTERPhysical Properties

Can be observed or measured without changing the chemical makeup of the substance.

Examples include: Color, Density, Taste, Texture, MassChemical Properties

Can be observed only in chemical reactions involving the substance.Examples include: Ability to rust, flammability

Characteristic PropertiesAre very specific to each type of matter, like fingerprints. They are

UNIQUE to that substance and are used to identify matter. Examples include: density,melting, boiling and freezing points, and

conductivity

Melting point, boiling point, and freezing point are all examples of what kind of property?

Why?

CHARACTERISITC PROPERTIES BECAUSE THEY ARE UNIQUE TO THAT

PHYSICAL PROPERTY because it is used to describe a substance BUT it is not a characteristic property because

these things are not unique to that substance.

Shape, volume, and mass are examples of what kind of property

and why?

CHEMICAL PROPERTY because it is used to describe a substances ability

to react with another substance.

Flammability, rusting, reacting with water are examples of what

kind of property?

PHYSICAL PROPERTIES• Besides density, boiling point freezing

point, melting point, condensation, taste, color…. Are there any other examples of physical properties?

Malleability

Ductility

Conductivity

Hardness

Elasticity

Solubility

CHANGES IN MATTER

PHYSICAL AND CHEMICAL CHANGES

A physical change is when there is a change in the matter but NO NEW substances are formed.

What are some examples?

Usually there is a change in the SIZE, SHAPE, or STATE that the matter is in… remember… no new substances are formed/produced!

HINT: Usually, physical changes are reversible

CHANGES IN MATTER

• A chemical change is a change in matter where NEW substances are formed.

• How do you know that a new substance has formed?

The properties of the matter have changes! Like …color, density, boiling pt, solubility, etc.

HINT! Usually, chemical changes are NOT reversible.

CHANGES IN MATTER

It is sometimes difficult to tell whether a chemical or a physical change has occurred. Here are some clues that might help:

» Burning always indicates chemical change» If a NEW color appears, it is a chemical change» A change in the state of the matter indicates a

physical change. Do not get confused with gas production which is a chemical change.

» Dissolving is a physical change…it is reversible
