Matter

What is Matter? Matter is anything that has mass and volume It occupies space composed of atoms Everything is made of matter

A property describes how an object looks, feels, or acts. Its used to identify a substance

Properties Luster- how shiny or it reflects light Color Odor Luster- how shiny or it reflects light Malleability- able to be beaten into a thin sheet Ductility- ability to be pulled into a wire Conductivity- ability to transfer heat or electricity Hardness- how easily a substance can be scratched

Properties Melting Point/Freezing Point- temperature at which the substance reaches the solid and liquid phases Boiling Point- the temperature at which liquid will become a vapor Density- the ratio of mass of a substance to volume Mass- the amount of matter in a object Volume- the amount of space a substance occupies Length- distance between two points Combustibility- ability to burn

Identification properties must be used in combination to adequately describe a kind of matter all colorless liquids aren’t water Each type of matter must be described by several properties, both chemical and physical

Classification of Matter To better understand matter we will organize what we know into a chart

Not Separated Physically Matter Mixtures heterogeneous homogeneous Substances Element Compounds Types of Matter Not Separated Physically Separated Physically Different Throughout Same Throughout Only One Type of Atom More than One Element

Mixture Made up of more than one kind of matter Can be separated physically by: Evaporation Filtering Sorting Electric Charge

Heterogeneous Mixture You can see different parts

Homogeneous Mixture Appears to look similar throughout because substances are so evenly mixed

Substances A single kind of matter Its pure Has a specific set of properties

Compounds a substance made of two or more elements Cannot be broken down physically Can be broken down chemically

Elements A pure substance that cannot be broken down into any other substance
