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 _________________

What is matter continued Matter = Mass = use a balance to find 

Basic Building Blocks of Matter _____________ and ____________ are fundamental building blocks and they make up elements and compounds Atom: Element: Compound:

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 Properties Physical Properties: a characteristic that can be observed or measured without _________ ______________________________________ Examples from baggie lab:

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 compounds 1.Every sample of a given pure substance has _____________________________________ (physical and chemical) 2.Every sample of a given pure substance has _____________________________________
