Chapter 1-2 Matter and Its Properties

Is Air Matter?

What is matter?

• Explaining what matter is involves finding properties that all matter has in common which can be difficult because matter has different forms

• All matter has _________________• All matter has _________________

What is matter continued

Properties and Changes in Matter

• Characteristic Properties: used to identify matter by distinguishing between substances.

• Some properties characterize a whole group.• Extensive Properties:

• Intensive Properties:

Baggie Lab and Physical Changes

• Physical Chage: a change in a substance that _____________________________________

Examples from baggie lab:

Change in State

• Change in state:

Change in state

Solid

• Definite volume and definite shape

Liquid

• Definite volume, indefinite shape. Assumes shape of the container

Gas• Neither definite volume nor definite shape.

Takes shape of entire container

Plasma• High temperature physical state of matter in which

atoms lose their electrons. Found in fluorescent bulb.

Chemical Properties

• Chemical property:

• Example: _____________________by combining with oxygen, _______________________by combining with sulfur

Chemical change• Chemical change or chemical reaction =

• ________________: the substances that react in a chemical change

• ________________: the substances that are formed by the chemical change

Chemical changes

• Chemical changes like (combustion and decomposition)___________________________________________________________________________________________________

• BUT

Classification of Matter

• Example: Think about the Nuts and Bolts activity, which bag contained the mixtures? Give an example, and explain why!

• ___________________: a blend of two ore more kinds of matter, each which retains its own identity and properties

Mixtures

• Pizza, salad, trail mix, kool aid, shaving cream,

Types of Mixtures

• Homogeneous:

Examples: solutions: a homogeneous mixture of a liquid like Kool aid

• Heterogeneous:

Examples: clay and water

Ways to separate a mixture:pg. 16

Pure Substances

• Pure substance:

• Either elements or compounds1.Every sample of a given pure substance has
